These ...
The ore then goes through smeltering and converting and the process ends with the refined ore being made into copper plates ready for sale to the world market (Figure 1) (2,3,4). This type of mining produces many harmful products such as sulfuric acid and sulfur dioxide along the way.
Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process .It is a high technological enterprise that integrated research, manufacture, sales and service .

The ore is crushed and stacked into specially designed pads. The pads are lined with synthetic or natural materials such as polyethylene or compacted clay. Acids are introduced to copper-bearing ore, seeping through and dissolving copper and any other metals, including radionuclides. The liquid that "leaches" through the rocks is collected.

Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.
unique to a particular ore body. This paper generally describes copper, lead, and zinc mining operations and their associated process wastes and residues. This description can serve as a basis for identifying those process residues and waste that contain both impurities and products which currently cannot be economically recovered.
We supply best Copper Ore, which is widely accepted in many mechanical companies to embed sturdiness. This ore is best in purity and completely safe to handle with bare hands. This ore is resistant to distortion due to high heat, pressure and environmental factor.
Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 percent copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80 percent of global copper production is ...
Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
