Method of extraction of metals from low grade ores

BACKGROUND OF THE INVENTION. This invention relates to a process for the extraction and recovery of metals from ores, particularly low grade ores, by grinding the ores to an extremely small particle size, forming a substantially homogeneous aqueous slurry of the particles, and extracting metals from the slurry with a solvent in a counter-current liquid-slurry extraction step.

Gold extraction Wikipedia

This is typical of low-grade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure

Low grade ores Smelt, leach or concentrate? ScienceDirect

Jan 01, 2010 Bacterially-assisted heap leaching of low-grade copper sulphides is a developing technology that has been applied successfully to the extraction of copper from sulphide minerals such as chalcocite at ore grades down to 0.15% ( Watling, 2006 ). The ore is typically crushed to about 6–13 mm prior to stacking into heaps.

Gold Recovery And How To Choose The Right Process

Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low grade and high grade
