The overflow ball mill is a type of ball mill commonly used as a grinding machine in mineral processing plants. It mainly comprises a cylinder, end cover, main bearing, hollow journal, transmission gear, and ore feeder. The barrel of the overflow ball mill is welded with a steel plate with a thickness of 15-36mm.

Heap leaching of ore grades in the range of 0.5 to 3.5 g/mt Au (0.015 to 0.100 oz Au/ton) is the method of choice for ores from the surface mine and for some ores from underground workings. For the ore mined containing gold grades above 3.5 g/mt Au (0.100 oz Au/ton) is processed in the mill to provide optimum overall recovery and …

Grinding is usually performed in a ball mill for the purpose of reducing the ore to sufficient fineness that the gold particles may be exposed to the dissolving action of the cyanide solution. This dissolving action may begin either in the ball mill or in the agitators. In the former case, the grinding is done in cyanide solution.

Fluorite ore flotation is a method of extracting fine-grained disseminated fluorite ore by means of flotation beneficiation. This method is mainly used to produce high-quality chemical grade fluorspar concentrate. Due to the higher requirements on the concentrate grade, it is also the only way to produce chemical-grade fluorspar powder ore.

Messages. 5,191. Location. Rhodia Drive. Aug 2, 2008. #3. In low concentrations cyanide is good for gold and silver. The more you put in typically the more it will pull out in the form of base metals. Even then though, it's not as if you can't wash/dissolve those out from material cemented from gold and silver cyanide.

Its major purpose is to perform the grinding and blending of rocks and ores to release any free-gold that is contained within them. At major mines, the mill was the critical equipment that was required to process the ores that were extracted from deep underground. Many early mines used stamp mills, but many operations today find that …
