CuSO<sub>4</sub>.5H<sub>2</sub>O ; blue; triclinic; loses 5H<sub>2</sub>O at 150 degrees C; white when dehydrated; slowly effloresces in air. Used in ore flotation and as a source of copper.
Industry:Mining
CuTiO<sub>3</sub>. Sometimes added in quantities up to 2% to BaTiO<sub>3</sub>to increase the fired density.
Industry:Mining
Cuts characterized by the drilling and ignition being done so that all the holes can cooperate and break smaller top angles. They are called instantaneous cuts because they are preferably ignited by instantaneous detonators to ensure a simultaneous detonation of all the charges in the cut. Some examples are Blasjo cut; WP-cut.
Industry:Mining
Cutting ring at the entry to a pipe feeding into a suction cutter dredge. Set of cutting blades in dredge trommel used to break clay brought up by dredge buckets.
Industry:Mining
Cylindrical drum, which rotates slowly through trough-shaped bath, fed continuously with thickened ore pulp.
Industry:Mining
Cylindrical tank with obtuse conical base around which raking gear moves slowly, pushing settled sludge to a central discharge. In the body of the tank hang radially mounted tube frames covered with filter cloths (socks). These are connected with a central valve and timing mechanism, so set that vacuum is applied for 1 to 10 min to 1340 remove filtrate, after which the gathered solids are displaced by a brief flushback so that they fall to the raking zone.
Industry:Mining
Cylindroconical ball mill, made in three sections--a flattish cone at feed end followed by a cylindrical drum, and finishing with a steep cone leading to the discharge trunnion. The tricone mill has wedge-shaped liners in the drum section that turn this into a gentle conic frustrum widest at the feed end.
