If you are looking to extract gold from refractory low-grade ores, we are introducing a game-changer to the entire gold mining industry. Your reserves containing refractory gold considered below the cut-off grade are not considered reserves because the cost of extracting it using pressure oxidation and bioleaching is too high.

One may notice that, when the NF90 membrane is used for filtration of effluent from gold mining with a RR of 70%, there will be a 77% decrease in permeate flux in comparison to initial water flux through a clean membrane. Of these 77%, 30% are due to concentration polarization, 15% to reversible fouling formation and 32% to irreversible fouling formation. The high percentage …

Filtration is a physical separation process that separates solid matter and fluid from a mixture using a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate. Oversize particles may form a filter cake on top of the filter …

A gold mine, for example, uses over 1 million US gallons of incoming water each day. This simple reality can place stress on the environment and surrounding communities. Water supply, scarcity and regulatory constraints are changing the landscape of mine site water management. As such, mining companies use complex water management plans to minimize the potential for water …

Such ores are referred to as refractory, and they frequently contain the sulfide minerals pyrite, pyrrhotite, or arsenopyrite. Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. The most common method is to roast gold-bearing minerals at temperatures of 450° to 750° C (840° to 1,380° F) to ...
