Selective froth flotation concentration of antimonite ore from a mixture of antimony, lead and arsenic ores. Abstract. Mineral ore beneficiation and value addition has become a key factor for economic growth in Africa. Froth flotation process is used to concentrate relatively low grade ores. In. Zimbabwe antimonite is mined.

When appreciable amounts of antimony in the form of the minerals stibnite and/ or berthierite are present in the flotation concentrates, the recovery of gold is lowered depending on the amount of antimony present. The higher the antimony content, the lower the gold recovery. Generally speaking, up to 1% antimony can be.
