Copper Mining and Extraction Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is

Mining Industry Copper Sulfide Ore and Flotation Process

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.

Sulfide ores. Secondary sulfides those formed by supergene secondary enrichment are resistant to sulfuric leaching.These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using

The effect of grinding conditions on the flotation of a

Nov 01, 2003 The impaired flotation performance of the ore ground in the ceramic mill may be attributed to the morphology of the particles, submitted to longer abrasion action (29 min in the ceramic mill × 16 min in the lined mill with high chromium rods). Another explanation could be the precipitation of oxidised copper and iron species on the sulphides

The content of copper sulfides in ore samples varies from 3.32 to 7.29%; the relative portion of copper sulfide in a form of tennantite in different samples of deposit varies from 29 to 93%.

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Sulphide ores Mill (Grinding) Chemistry

Sulphide ores. The copper sulphides are divided into three types: a) pure sulphides (chalcocite and covellite). b)copper and iron sulphides (chalcopyrite and bornite). c) complex sulphide (enargite) The chalcopyrite copper ore is more widely distributed. The pulp from the mill, is introduced into flotation cells. From the bottom of the

Acid leaching of oxide–sulfide copper ore prior the

Oxide–sulfide copper ore was sampled from the ore body Cerovo C1 (south deposit) and used in this study. The chemical composition of the ore sample is pre-sented in Table 1. From Table 1, it can be seen that the high copper concentration is in the sample, as well as the high copper oxide content, while the sulfide copper concentration is lower.
