    Jul 01, 2017· Cinnabar, mercury sulfide (HgS), is the principal ore of mercury. (more below) Cinnabar is very dense, 8.1 times as dense as water, has a distinctive red streak and has hardness 2.5, barely scratchable by the fingernail. There are very few minerals that might be confused with cinnabar, but realgar is softer and cuprite is harder.

    There are two main types of copper ore of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined, though they are processed in different ways.

  • What is Sulfide Mining Mining Action Group

    Metallic sulfide mining (aka hard rock mining) is the pract of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water

    Typically, the sulfide body is a concordant lens underlain by a discordant stock or stringer zone with vein-type sulfide mineralization (fig. 7–1) (Galley and others, 2007). Based on the shape and depth of the ore body, the sulfide content in the ore produces significant geophysical signatures.

  • Mining 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.
