Depressing Species

The formation of hydrated, oxidized surface species like iron hydroxide and basic sulfates, increases particle hydrophilicity, and will thus depress flotation. High thiosulfate levels, which may arise when milling under relatively nonreducing conditions, e.g. fully autogenous grinding, or laboratory grinding in porcelain mills, may lead to the precipitation of insoluble thio-salts, which may also depress flotation. The generation of soluble sulfide species, especially notable in stagnant, anaerobic water reservoirs with bacterial action, may lead to mineral depression, since the sulfide and xanthate ions compete for the same surface sites.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
