Gold Extraction & Recovery Processes
A variable in the flotation circuit design is to include column cells in the cleaner circuit in order to improve the gold concentrate quality and to reject insoluble material. Column cells are particularly important when the ore present high content of silicates, carbonates and clays, which affect thickening, filtration and concentrate grade.

Ask MGS: What are Gold Concentrates?
Better known as "pay dirt," gold concentrates are sourced in two different ways. The first is through gold panning (or other techniques that use gravity separation). When panning for gold, the objective is to separate the particles of dirt from the heavy particles of gold. In most cases however, gold is not the only heavy material in the pan.
