The History of Copper Mines

Copper is a typical pro-sulfur element, which in nature mainly forms sulfides, only under strong oxidizing conditions to form oxides, and under reducing conditions to form natural copper. Copper minerals and copper-bearing minerals have been found on the earth’s crust about more than 250 kinds, mainly sulfides and their similar compounds and copper oxides, natural copper and copper sulfates, carbonates, silicates and other minerals

Copper mining usually adopts two methods: open-pit mining and underground mining. Open pit mining is carried out by stripping surface rocks and uncovering copper deposits; Underground mining refers to the mining method of excavating or excavating underground to obtain valuable minerals.

As early as 3000 BC, the ancient Egyptians began using copper. They melted the copper ore into copper ingots, which were used to make weapons and decorations. Subsequently, the mining of copper mines rapidly developed in Israel, Egypt, Rome, Greece, and ancient India, and it was also used to make copper utensils, pots and pans, and other items.

Copper is a typical pro-sulfur element, which mainly forms sulfides in nature and only forms oxides under strong oxidizing conditions and natural copper under reducing conditions. About 250 kinds of copper minerals and copper-bearing minerals have been found on the earth’s crust, mainly sulfides and their similar compounds and copper oxides, natural copper and copper sulfates, carbonates, silicates and other minerals. Among them, there are 16 kinds of minerals that can be used as raw materials for industrial minerals in suitable selection and metallurgy conditions. That is, natural elements: natural copper (containing nearly 100% copper).

Malachite often results from the supergene weathering and oxidation of primary sulfidic copper ores, and is often found with azurite (Cu3(CO3)2(OH)2), goethite, and calcite. Except for its vibrant green color, the properties of malachite are similar to those of azurite and aggregates of the two minerals occur frequently. Malachite is more common than azurite and is typically associated with copper deposits around limestones, the source of the carbonate

The first stage of any process within a metallurgical treatment circuit is accurate grinding or comminution, where the rock is crushed to produce small particles (<100 μm) consisting of individual mineral phases. These particles are then separated to remove gangue (rocks residues), thereafter followed by a process of physical liberation of the ore minerals from the rock. The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores, both secondary (supergene) and primary (hypogene), froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergene native copper, this mineral can be recovered by a simple gravity circuit.

After mining, copper ore needs to undergo refining treatment in order to obtain high-purity copper. Generally, smelting method is used to separate copper ore and process it into copper concentrate, bronze, flux, etc. In addition, electrolysis, alkaline separation, and chlorination methods can also be used to refine copper ore.

Copper is a metallic element that has a high economic value and is the main raw material for the production of copper. Copper mining helps to promote economic development and also provides more opportunities for the world economy.

Copper is a critical component in electric vehicles, used in batteries, wiring, charging points, and more. It’s also used in batteries for energy storage, as well as in generating wind and solar power.

What does malachite look like? Does it have the same thing as a peacock? Malachite is a beautiful emerald green and is so named because of its resemblance to the color of peacock feathers.

In Pakistan our prospectors are going to mine fields to get copper concentrate.
On site, our customers packed the copper concentrate in airtight bags; the next step was to pack and transport it to China for trading.

Copper ore refers to the general term for natural mineral aggregates containing copper that can be used. Copper ore is generally an aggregate of copper sulfides or oxides with other minerals that react with sulfuric acid to produce blue-green copper sulfate. The industrial minerals of copper are: natural copper, chalcopyrite, pyroxene, zoisite, blue copper ore, malachite, etc.

Transported to storage sites in China where copper concentrate is being cared for in storage

The beneficiation process of copper ore is mainly crushing – ball milling – classification – flotation – selection, etc. For rare and precious polymetallic ores such as nickel, cobalt, molybdenum and gold, the rough copper concentrate can be separately flotated for nickel concentrate. ore, cobalt concentrate, molybdenum concentrate, gold concentrate.

Malachite is more common than azurite and is typically associated with copper deposits around limestones, the source of the carbonate.

Copper ore research and mining in China is mainly through underground mining and open pit mining. In terms of the amount of ore mined so far, underground miningaccounts for 44.6%, and open pit mining accounts for 55.4%.
