REFRACTORY ORE PROCESSING. The common definition of "refractory" gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.
Mineral processing theory rate of recovery (%) = concentrate grade * (raw ore grade - grade of tailings) / ( raw ore grade * (grade of raw ore concentrate grade - grade of tailings)) * ... = gold concentrate gold ore gold content (g) / (g) * . ... Galena ore mineral processing process technology and Galena ore beneficiation plant.
Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.

Sensor-based ore sorting transforms the bottom line in gold mining Exploring gold ores becomes more challenging every year. Mines increasingly deliver lower grades and complex mineralogy, forcing mills to process more material and thus compounding the expanding ratio between these tonnages and the ounces of ore produced.
Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...
