GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
Well tech International Mining Equipment Co.,Ltd. is a large benefication service company specialized in designing, manufacturing, installing and debugging of benefication equipment as well as providing flow sheet design and plant design.
The present paper describes the beneficiation of low grade gold ore by flotation columns and the implications of improved metallurgy on subsequent cyanidation. 2. EXPERIMENTAL 2.1. The gold ore The mineralogical assay of gold ore revealed that the ore is semi refractory containing both free and refractory gold approximately in the ratio of 80:20.
Pre 19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
