Froth flotation Wikipedia

In the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, [21] requiring

EDTA-enhanced cyanidation of refractory bio-oxidised

01/05/2020· In this paper, ethylenediaminetetraacetic acid (EDTA) was used to activate refractory bio-oxidised flotation gold concentrate and improve gold extraction efficacy during alkaline cyanide leaching. The results showed that EDTA activation influences physico-chemical properties such as particle size distribution, surface area and mineralogy, rate and yield of

Gold extraction Wikipedia

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values. Generally, recovery of the gold from the sulfide concentrates requires further

Sulphide Gold Ore Treatment by Leaching and Flotation

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

Improved recovery of a low-grade refractory gold ore

01/07/2014· Often, the gold bearing ores are refractory due to the gold grains and concentration by flotation is necessary, either followed by roasting, bacterial leaching, or pressure leaching in a way that the gold is liberated prior to cyanidation. Two basic initial approaches are available, either treating the whole ore or processing some form of concentrate into which a high proportion of the gold

Gold Extraction from a High Carbon Low-Grade Refractory

A concentrate containing gold 7.26 g/t and carbon 12.37 % was obtained, with gold recovery 83.10 % and carbon recovery 90.24 %. Subsequently, the roasting of flotation concentrate favorably made the removal rates of carbon and sulfur reach 99.81% and 98.79%, respectively. After roasting, the gold in the roasted product was further enriched to 29.70 g/t and the optimal gold cyanide leaching
