Jul 16, 2014 During roasting, refractory gold ore is treated with extremely hot air. This causes the sulfites to oxidize, separate from the ore, and become sulfur dioxide. Once all of the sulfides are oxidized, the remaining gold ore can be processed normally. The roasting method has been around for hundreds of years. Prior to the 20th century, the process.Flotation is a widely used method of concentrating ores, and it is believed to be the most commonly used ore dressing process. It is based on the fact that when air bubbles are introduced into a ground ore pulp, particles of some minerals will become attached to the bubbles, whereas other minerals will not become so attached and remain in the pulp.

The gold ore process is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, the gold ore process lowers the gold mining operation cost and increases the gold recovery rate to a degree of 99 .The actual dosage should be calculated based on the concentration of the slurry. Also the property, grade of the ore and pH of the slurry also can affect the dosage of CNLITE gold dressing agent. Add Method It can only be used after it is fully dissolved in normal temperature water. The rate of dissolution is usually accelerated in running.

The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized.The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold ( 10 m).
