Gold ore can be classified as free-milling, complex, or refractory and each type of ore has different challenges when it comes to processing methods. Cyanidation with CIL/ CIP continues to be the most common method, although there are environmental concerns due to toxicity.

The reason of the gold mineral refractory There are so many types of reasons that caused the difficulty of gold ore processing, including physical element, chemical element, and mineralogical element.

This relies on the difference in densities between the ore minerals and the gangue. This method has applications in various stages of a flowsheet; from initial processing to final upgrading. Some of the earliest methods were utilized by the prospectors of the gold rush where they used simple panning techniques to concentrate their ore.

The problem a Small Gold Processing Plant can solve is for the need to to provide a small, relatively simple and inexpensive gold mill that will operate at a reasonable profit with a minimum of supervision.

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation ...

Treatment of Refractory Gold Ores Extractive Metallurgy Once the cause has been identified, there are a number of alternatives for treating the ore. Firstly, the gold can be made more amenable to cyanidation by ultra-fine milling, followed by a hot atmospheric leach –the Albion Process.

REFRACTORY GOLD. By definition, refractory gold ores contain gold that is resistant to extraction by conventional chemical processing and as a result responds poorly to traditional gold cyanidation techniques such as Carbon-in-Leach (CIL), yielding less than 80% of the contained gold.

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Improved ways to crush and process the ores were developed in Europe during the Industrial revolution, and ore processing ceased to be magic and came into the realm of science. Yet it was only from the push of the great gold rush waves of the new world, which began in the mid 1800s in California, that real progress was made.

Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.
