Sulfide mining is the process of extracting trace amounts of copper, nickel and other metals from sulfide-bearing ores, which produces sulfuric acid. This is the same as battery acid. In addition to acidifying lakes and rivers, sulfuric acid leaches out heavy metals such as mercury, lead, arsenic and other toxins from the rock to produce acid ...

Jul 09, 2019 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Arsenic can exist in sulfide minerals either as a dominant mineral-forming element or as an impurity. Arsenic release into nature is a slow process as a result of mineral weathering; however, physical forces such as grinding, crushing, and pulverization from mining activities greatly increase the release rate.

It would be of interest to examine the ore by microscopy after the bioleaching test, to evaluate whether the leaching was inhibited due to passivation of the particles, which is a common issue in leaching of sulfide minerals, especially chalcopyrite. The authors do not suggest any process for recovery of Cu, Ni and Co from the pregnant solution.

Nickel processing Extraction and refining Britannica

Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore.

Jul 16, 2021 01 Copper-nickel sulfide ore extraction methods. For the copper-nickel sulfide ore, the copper mainly exists in the form of chalcopyrite, while the nickel mainly exists in the form of free nickel sulfide, such as nickerpyrite, millerite, violarite. And a considerable amount of nickel ore occurs in the pyrrhotite as the isomorphism.

To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) . In the concentrating operations these minerals are separated from the gangue material of the ore, that might contain as little as 0.5% copper to form a concentrate ...

Oct 26, 2020 In production practice, the commonly used process for beneficiation of gold-bearing sulfide ore is: flotation first, and the flotation concentrate can be directly cyanidized, or re-grinded and then cyanidized, or treated with gravity separation and amalgamation. For the gold ore dressing plant, try to adopt a mature and simple production process.
