The first sample was mining (coal) refuse (overburden and waste rock, raw tailings), extracted at low levels, comprising top soil and overburden, waste-rock, and low-grade minerals. High volumes of these inert materials are found piled in slag heaps in the area around the coalfield (Figure 2b). The other three samples (“tailings”) consisted of coal refuse from coal-flotation treatments that extract the coal fromRead More
It is important to remember that there are four stages in the life cycle of a mineral: (1) geological mineral deposits are mined and processed into refined materials, (2) refined materials (few if any minerals are economically interesting as mined) are subsequently utilized in either civilian or defense manufacturing industries to produce end products, which are (3) used for a certain periodRead More
