Refractory and Non-Refractory Ore - Gold Companies

Whether gold is refractory or non-refractory has a huge bearing on a potential mine's viability. A deposit with a resource similar or larger than that of existing mines, could be rendered un-viable if testwork identifies that the ore is refractory. This means that when looking at resources a company maybe quoting, it is not enough to take note of the grade, but we must consider the processing ...

Gold Ore - an overview ScienceDirect Topics

Gold ores are classified “free-milling” and “refractory” based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an appropriate ...

Establishing thE ProcEss MinEralogy of gold orEs

Gold ores are commonly classified by the metallurgist into two major categories: free-milling and refractory ores. Typically, free-milling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. Refractory ores are defined as those that give low gold recoveries or give acceptable gold recoveries only with the use of significantly more reagents or ...

What is Gold Ore worth? High Grade Mining Ore

Another thing to consider, is that the gold within many ores is microscopic particles, which require advanced methods to extract, such as through cyanide leaching. Extracting gold from this type of ore is feasible for multi-million dollar mining companies, but almost impossible for the average person to do. Also consider that gold concentrations in ore is never consistent, often occurring in pockets rather than consistently throughout. So a mine that produces some high-grade ore
