mill fine grinding technology gold

Grinding refractory gold ores to below 20 microns and finer, whilst liberating more gold, also liberates many other mineral species which affect the oxidative and cyanide downstream process. In many cases when only ultra fine grinding is used a maximum recovery is reached and grinding finer actually reduces the precious metal recovery. Application Range. With scientific reasonable design and abovementioned unique advantages, HLMX ultra-fine vertical mills are applied widely in metallurgical, chemical, and non-metallic industry, for grinding of various materials, such as limestone, gypsum, coal, barite, calcite etc.

Grinding refractory gold ores to below 20 microns and finer, whilst liberating more gold, also liberates many other mineral species which affect the oxidative and cyanide downstream process. In many cases when only ultra fine grinding is used a maximum recovery is reached and grinding finer actually reduces the precious metal recovery.

The grinding efficiency is low, the energy consumption is high, and the product is easily crushed, which affects the sorting effect and economic benefits. Practice has shown that the more difficult to grind the ore, the less economically reasonable it is to use one-stage grinding process for fine grinding.

Automated sorting technology was just the first stage of advancement at Mt Todd. The combined use of x-ray transmission (XRT) and laser sorting technologies enabled innovation in the grinding circuit at Mt Todd. Vista Gold has re-designed the grinding circuit at Mt Todd to increase gold recovery while at the same time lowering the use of energy.

An ultra-fine grinding (UFG) circuit of eight FL VXP mills has been successfully optimised at the Barrick-operated Kibali gold mine in the Democratic Republic of Congo. The first four VXP mills were installed in the Kibali gold recovery plant in 2014. Four additional units were added in 2017, in line with changing from dual oxide-sulphide
