Red coltan ore processing in sodium cyanide price the mine main ingredients for Fe2O3, oxidizing coltan ore processing. Fe2O3 in nature as variants known there are two more homogenous, namely alpha Fe2O3 and gamma Fe2O3, in which the mass fraction of Fe is about 69.9433034300%. The former is stable under natural conditions, known as red coltan ore processing ore; Is better than the latter under natural conditions of alpha stable Fe2O3, in metastable state, called a magnetic red coltan ore processing ore. Often contain classes with foreign matter like Ti, Al, Mn, Fe2 +, Ca, Mg, and small amounts of Ga and Co. Trigonal system, perfect crystal rare. Crystal red coltan ore processing ore for steel gray, hidden crystal; Earthy red coltan ore processing ore red. Streaks of cherry red color or fresh pork liver. Metal to a half metallic luster. Sometimes tarnish. Hardness 5 ~ 6. The proportion of 5 ~ 5.3.
Red coltan ore processing mineral aggregate has gold heap leaching various forms, form some mineral subspecies, namely:
(1) mirror coltan ore processing ore for metallic luster of the rosette or flake red coltan ore processing mineral aggregate.
(2) mica red coltan ore processing mineral metallic luster of fine crystalline scaly red coltan ore processing ore.
(3) the oolitic or reniform red coltan ore processing mineral form of oolitic or kidney shaped red coltan ore processing ore.
Red coltan ore processing is ore is widely distributed in the nature of coltan ore processing one of minerals, can be formed in various geological processes, but by hydrothermal process, sedimentation and regional metamorphism. In the oxidation zone, bare coltan ore processing ore can be made of brown coltan ore processing fiber coltan ore or ore processing ore processing, needle coltan ore mine, the dehydration effect. But can also become a needle coltan mine ore processing and water chek coltan ore processing ore, etc. Under the condition of reduction, red coltan ore processing ore can be transformed small gold wash plant into a magnetic coltan ore processing ore, said illusion magnetic coltan ore processing ore.
