The fourth class of gold ores comprises the gold-telluride group. The gold telluride ores occur with silver or with silver lead and antimony or as native gold accompanied by other tellurides. These ores are often sent direct to the smelters for treatment. A fifth type is the disseminated ore type. They are often low in grade but large.
General Types of Gold Ores Gold deposits are often classified according to their association. The first of these may be catalogued as quartzose. This implies that the gangue mineral is acid that is quartz and that fluorite may abound or even the other gangue minerals of the alkaline earth group.
Cyanide-Free Gold Separation. February 2011. Some oresmostly those with a high free gold contentare very amenable to gravity concentration. Well oxidized ores containing coarse gold are usually best for non-cyanide processes. Ores with significant sulfide content may require the.

Sep 02 2011 The problem is that gold occurs in many types of deposits and what indicators work great for one type of deposit dont always work well for another. As an example in some places the presence of vein quartz on the ground is a valuable indicator yet I have been in places where there is so much vein quartz everywhere that is worthless as an .
gold ores can be classified into 11 types Table 1. Some metallurgical implications to these gold ore types are summarised below Placers quartz vein gold ores and oxidized ores Generally placers quartz vein gold ores and oxidized ores are free-milling and gold can be recovered by gravity andor direct cyanide leaching.
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 .

Gold ore. Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies for gold ore of different characteristics such as flotation cyanide leaching gravity separation etc. to achieve the processing plant of optimal and cost-efficient process designs.
Crushing the ore can free the gold and allow recovery by gravity-based methods. In fact its very common that the gold in hard rock ores will range in the 30- to 200-mesh size range with most of the gold in the lower end of that range. The tried and true method for testing these ores in the field is hand crushing and panning.
