Ore WikipediaAn ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The ore grade, or concentration of an ore mineral or metal, as ...
Sodium Isobutyl Xanthate(SIBX) CHEMPIONEER LIMITEDSodium isobutyl xanthate is also a stronger collector in the flotation of various nonferrous metallic sulfide ores. Sodium isobutyl xanthate is mainly used in flotating copper, lead, zinc ect. sulfide ores. It has displayed especially effective in the flotation of copper ores and of pyrites in natural circuits.
Types of Ore | The richest grade of copper ore is native copper, which is pure copper (). Many metallic ores occur as sulfide minerals. Examples of sulfide minerals are galena (lead sulfide, PbS), sphalerite (zinc sulfide, ZnS), covellite (copper sulfide, CuS), or pyrite (iron sufide, FeS2).
