Whether it’s Polar Mining, the metal smelting plant of Melens Mining, the rare earth refinery at Lugang’s tailings pond, the tailings treatment plant at Kendecock, or the e-waste incineration plant on Bear Island, all those who complete the final metal refining

They are all system melting pots.

The processing and production of gold ore is generally divided into two categories: wet method and fire method. Whether it is wet method or fire method, crushing, screening and grinding must be carried out in the early stage.

The basic procedures for ore processing in Northwest Mining are as follows:

The ore from the mine is first crushed into pieces by a jaw crusher.

Gold mines are associated minerals. Although these ores are called gold ores, their components are mostly pyrite, chalcopyrite, galena, pentlandite, etc. The metal components are iron, copper,

Silver, lead, zinc, sulfur, nickel, chromium...

The broken lumps of ore continue to enter the huge grinder and are ground into fine powder. These fine ores will be magnetically separated to select the iron ore with the most components and then enter the grinder again to grind into fine particles.

The size of these particles will reach millimeter or even micron level, and then enter the flotation workshop.

During the flotation process, different chemical agents will be added for activation, foaming, and collection, thereby selecting useful minerals and becoming the concentrate of the mixture.

Take Northwest Mining's metal smelting plant in Rustenburg as an example. They process 15,000 tons of ore every day, and the final concentrate is only over 300 tons, with a concentrate yield of less than 3%.

These more than 300 tons of concentrate will contain 50 to 120 grams of precious metals per ton, and are then sent to the roasting furnace for heating and concentration. This process will evaporate the water and some oxides, increasing the precious metal content to 1,000 to 1,800 per ton.

gram.

After the concentrated concentrate powder comes out of the furnace, it is continued to be sent to the electric furnace, where it is melted into a metal solution at a high temperature of 1350 to 1400°. Some metals will evaporate, and the solution leaves the electric furnace and is cast into large ingots.

There are still copper, nickel and other elements in it.

Next, these ore ingots will enter the process of refining gold and platinum, and the refining and production links will be carried out in chemical workshops with higher security levels.

These workshops are surrounded by power grids, with monitoring systems installed in every corner. Security personnel patrol key locations, and employees must be searched when entering or exiting.

In the chemical workshop, heap leaching is used to first refine gold, and then to refine platinum group metals. The resulting slag can be further refined to extract the copper inside, or it can be handed over to other companies for processing.

As for Melens' metal refining plant, the crushing, screening, magnetic separation, and flotation processes are basically the same as those of Northwest Mining.

However, the flotation process will be more extensive, because in this process, other people's approach is to extract concentrate, but Melens' goal is to remove impurities, which are sediment, nothing more than silicates, calcium carbonate and the like.

.

Therefore, Northwest Mining can collect 300 tons of concentrate from 15,000 tons of ore, while at the Melens Metal Processing Plant, at least 500 tons of concentrate will be collected.

The next refining step is even more different.

Here at Melens Mining, there is no chemical treatment workshop, and no treatment processes such as heap leaching, mercury, and cyanidation are used. Instead, the system furnace is used to swallow the whole process in one go, without producing tailings or waste residue.

Even security and monitoring measures are not needed. The concentrate powder is transported from the flotation workshop to the concentrate warehouse using a loader and handed over to the mechanical servants.

The mechanical servants on duty will regularly summon the furnace to drain the concentrate and decompose it into gold, platinum metals, copper, lead, nickel, chromium, etc.

This kind of operation has a higher yield and a greater digestion and processing capacity.

As for benefits, regardless of gold and platinum, the harvested "base metals" such as copper, lead, nickel, etc. are also considerable. With such efficiency and benefits, who can compare with the system furnace?

Northwest Mining's profitability lies in its metal refining capabilities and higher yields than other companies. Their technologies are only used internally and are neither sold nor transferred. This is called a unique ability.

It is said that the precious metal recovery rate of Northwest Mining can reach more than 85%, and can reach as high as 90%.

This 85% to 90% yield is calculated based on 300 tons of concentrate as the denominator.

Melens' indicator is fixed at 80%, but the denominator is 500 tons. How do the benefits of the two compare?

Why did Northwest Mining block Melens Mining in the first place?

Because after Merens changed his boss, he increased the purchase price of ore by 5 points, and the price of ore per ton increased by about 1 dollar, and like a gold-swallowing beast, the development momentum is fierce. The production capacity of local mines is limited, and there is no room for two.

The gold-eating beasts have to survive together, so they do not hesitate to use extreme measures to shut down Melens Mining.

I never thought that the power and energy behind Melens was not weak at all. The northwest mining dog bit the hedgehog and was stung with blood.

Northwest Mining has become notorious in the industry. The directors of the Rustenburg Mining Company and the metal refining plant have all been detained, and the business has come to a standstill. The head of the Rustenburg Police Department was charged with participating in the robbery of five mines of Melens Mining.

The car is under investigation, and the police officers have been restricted from living there.

In short, the business in Rustenburg is already dominated by Melens Mining.

Back then, when the northwest mining industry was expanding, the method they used was to suppress them so that small mines would lose their living space.

Following Chen Lidong's instruction, Jipling adopted a method of giving profits and actively raising prices to help the mines in the Rand Basin increase production and obtain more profits.

The metal smelting plant in Melens is also adding equipment and increasing production capacity. If this continues, it will inevitably replace the position of Northwest Mining in the local area and become a big tree in the rainbow country's precious metal smelting industry.

...

Virgil was not idle either. He went to the country of Gaman and was responsible for taking over the Minahasa Gold Mining Company established by Newmont Mining in North Sulawesi Province of the country.

The Minahasa Gold Mine is located on the southeastern coast of the Minahasa Peninsula. Gold mining activities were conducted here 100 years ago during the Dutch occupation of Gaman.

In 1988, Newmont Mining Company discovered a gold mine in a place called Messel, 5 kilometers away from the Dutch mining area. The grade was as high as 10 grams per ton, and the gold content in the main vein could reach 60 tons.

After several years of research and analysis, Newmont Mining Company invested in Minahasa Mining Company here.

This company started mine construction in July 1994 and started production in June 1995. However, in just 6 years, it was ready to close due to depletion of ore resources and the company was about to cease production.

To invest in the construction of this mine, Newmont paid a lot of costs, including building a bulk cargo terminal with a 5,000-ton berth, training local villagers to become miners, building roads, and medical and health facilities.

The investment in the construction of mines and factories was 130 million U.S. dollars, and the investment in infrastructure in the following years was also 20 million U.S. dollars. However, the output value achieved in these six years was only less than 600 million U.S. dollars, barely making up the investment.

The original plan was that the mining work in this area would continue until 2026. However, due to excessive illegal mining in the area around Messel, after the Messel ore body was exhausted, the surrounding mines belonging to Newmont Mining's mining rights were no longer enough.

Keep metal smelters running.

Therefore, in June this year, Newmont Mining began negotiations with the Gaman government to terminate the original agreement to mine until 2026, because the original agreement did not consider the issue of closing the gold mine due to exhaustion of ore.

Now, things have turned around, and Virgil said he can take over Minahasa Mining Company and maintain production at the mining and metal processing plants.

After two months of investigation and research, Newmant signed a tripartite agreement with Virgil and the local government.

Virgil personally invested 60 million U.S. dollars to take over all the assets and interests of Minahasa Mining Company, and invested 20 million U.S. dollars to take over the mining rights of Newmont's unexploited mines.

Minahasa's production will continue until 2026, and existing employees will continue to serve the company's production and will not be laid off within one year.

Newmont Mining got rid of a burden and had a positive and proper explanation to the local government.

After the signing, Durant Epler, the vice president of investor relations who was responsible for handling this matter, said kindly in private: "Mr. Virgil, we have cooperated deeply in the matter of sniping at the northwest mining industry, and have achieved great results.

Big success.

This project is where you and I join forces again. As an old friend, I have to tell you that illegal mining of gold mines in the Minahasa area is very serious.

Moreover, those illegal gold miners used to be our employees. They learned some skills in our factory and dug pits nearby. After the ore was mined, they roasted it using local methods, which seriously polluted the environment.

The Minahasa County government has done nothing to deal with these matters, and a group of public officials are also involved in illegal mining.

Originally, the mineral deposits here could still produce for decades, but unfortunately we have lost interest.

Virgil, I hope you can handle these relationships well and find a good way to maintain the company. I wish you good luck."

Virgil shook April's hand and said: "Thank you, my old friend, I hope we can cooperate again."

After April left, Minahasa Mining Company, which had changed its owner, issued a notice: Collect ore! The grade requirement is above 1 gram per ton, and the price is 7..5 dollars per gram.

Many knowledgeable people were really shocked when they saw this news.

You must know that in the Minahasa area, the trading price of gold ore per ton is 7 dollars per gram of grade.

A metal refinery that changed owners actually raised prices by $0.50.

What’s even more confusing is that other people’s ore collection starts with a grade of at least 5 grams, and there is also a pricing rate requirement. The pricing rate for ores with a grade of 5 to 5.99 grams is 65%. For every 1 gram of higher grade, the pricing rate increases by 5%.

In other words, the price of gold ore with a grade of 5 grams can only be 4.55 dollars per ton. Only after it reaches 15 grams or more, the price will be calculated at 7 dollars per gram per ton.

The refining cost per ton of ore is approximately $0.50. Calculating this, the production cost of gold per ounce at the Minahasa Metal Refinery is likely to exceed $250.

$250 is the bare price, what about sales charges?

How to play with such a high cost?

As soon as the notice was issued, it can be said that one stone stirred up a thousand waves, and the small mine owners who worked hard to extract gold were also excited.

People are whispering that the new boss is probably a luolagebeng~.

Because the total cost of blasting, mining, and transportation for 1 ton of ore does not exceed $6, you can make money by transporting it here.
