Very fine scaly native copper that floats on water and is very difficult to save in milling.
Industry:Mining
Very fine-grained, generally sooty graphite from metamorphosed coalbeds. The word amorphous is a misnomer because all graphite is crystalline. The term has also been applied to very fine particles of flake graphite that can be sold only for low-value uses (such as foundry facings), and to fine-grained varieties of Ceylon lump graphite.
Industry:Mining
Very insensitive explosive that has a mass explosive hazard but is so insensitive that there is very little probability of initiation or of transition from burning to detonating under normal conditions of transport; large quantities, however, have a higher probability of detonation subsequent to burning; previously designated by the U.S. Department of Transportation as a blasting agent.
Industry:Mining
Very viscous; dark brown to black; liquid or semisolid; strong characteristic odor; sharp taste; translucent in thin layers; hardens with aging; sp gr, 1.03 to 1.07; boiling point, ranges from 240 to 400 degrees C; soluble in alcohol, ether, chloroform, acetone, glacial acetic acid, fixed and volatile oils, and sodium hydroxide; and insoluble in water. Chief constituents are complex phenols; also present are turpentine, rosin, toluene, xylene, and other hydrocarbons. Used in flotation.
Industry:Mining
Very weak oil or gas seeps, so weak that the deposition of material at the surface cannot be recognized without chemical analysis.
