Cyanide in the beneficiation of gold • % NaCNsolution is used to extract Au and Ag from ore • Au dissolves by two processes occurring simultaneously on its surface. Cathode • At one end of the metal, the hodiczone, oxygen takes up electrons and undergoes a reduction reaction. O2+ 2 H 2O + 2 e=> H 2O2+ 2 OHAnode
· INTRODUCTION OF BENTONITE: Bentonite is a kind of clay, often containing a small amount of illite, kaolinite, chlorite, Elo stone, quartz, feldspar, zeolite and calcite, which hardness is 1 ~ 2 and density is of 2 ~ 3g/cm3. According to the kinds of exchangeable ion, content and layer charge, bentonite can be divided into Na.
Beneficiation of marble from Griekwastad, Northern Cape Province by Mahumapelo* and C. Magaseng* Synopsis This paper is based on a study to determine the potential beneficiation opportunities for marble from Griekwastad in the Northern Cape Province. The marble was characterized mineralogically by Xray diffraction.
· Beneficiation techniques of highsulfurphosphorus iron ore Conclusion Vietnam's iron ore is widely distributed and abundant in reserves, but the comprehensive processing technology and economic level are relatively lower, resulting in the low utilization rate of iron ore resources, and even a large number of iron minerals are not developed.
Marble is a rock made of calcium carbonate which has been exposed to a natural recrystallization process.. Marble is being created by the transformation of other stones through the action of high temperatures and intense pressures. As a result of this process new minerals, textures, and structures give rise to a large number of different types of marble, as we will see in the examples below.

Many beneficiation techniques can be employed to upgrade the P2O5 grade of phosphate ores based on their characteristics in chemical composition and texture. The flotation process is most widely applied to balance the P2O5 recovery ratio and cost. In this review, the dominant techniques for the beneficiation of phosphate ores are introduced.

· Phosphate beneficiation plant In the treatment of phosphatic shales for recovery of phosphate, a simple low cost flexible flowsheet is highly desirable. Since all grades of ore from low to high P2O5 content may occur in a deposit it is important to consider the possibility of either mixing the ores or to segregate them into grades for separate treatment.
