Document Summary

Defining inorganic chemistry: organic chemistry study of compounds of carbon. Inorganic chemistry study of compounds of everything else (and some c) Accessing elements: the materials production process: natural resources contain desired elements, desired elements or compounds are extracted and purified, chemical process are used to convert extracted elements or compounds into desired chemical compounds. Our source of raw materials: earth: crust accessible raw materials, mantle minerals or iron, silicon, oxygen, outer core molten nickel/iron. Availability does not equal abundance: carbon, chlorine, lead, copper, sulfur (cid:374)ot (cid:373)u(cid:272)h i(cid:374) earth"s (cid:272)rust; availa(cid:271)le i(cid:374) concentrated forms in specific locations. Shaft mine subsurface: drift and slope mine are horizontal or sloping. Froth flotation: uses hydrophobicity diff b/w valuable minerals & waste gangue (use surfactants to maximize diff, steps, grind ore-containing mixture to powder, mix w/ water, oil, surfactants; beat into froth, ore is concentrated in the froth, skim off.
