ME551/GEO551 INTRODUCTION TO GEOLOGY OF INDUSTRIAL

An ore deposit is a well defined mineral deposit that has been tested and found to be of sufficient size grade and accessibility to be extracted mined and processed at a profit at a specific time Thus the size and grade of an ore deposit changes as the economic conditions change Ore refers to industrial minerals as well as metals.

PHASES OF A MINING PROJECT

The gold content of a good grade gold ore may be only a few one hundredths of a percent Therefore the next step in mining is grinding or milling the ore and separating the relatively small quantities of metal from the non metallic material of the ore in a process called

Activated Carbon in Gold Cyanidation

Activated carbon is a critical component in the beneficiation of gold ore allowing this widespread process to occur because of its ability to recover gold from the gold cyanide complex Depending on the deposit some silver ores may also be processed via cyanidation Here too activated carbon is the catalyst for recovery of this precious metal.

Measuring pH in Bacterial Oxidation of Metal Ores

Some gold ore deposits can be processed by simple grinding followed by extraction with cyanide but many refractory deposits contain gold that cannot be so easily separated The most common example of these ores contains sulfides the reduced form of sulfur A powerful technique for exploiting such low grade ore is called bacterial oxidation.

Gedabek Contract Area

Ore is crushed and then milled in a grinding circuit The finely ground ore is placed in stirred agitation tanks containing cyanide solution and the contained metal is dissolved in the solution Depending on the composition of the ore an option is available to process the finely ground ore through the flotation plant prior to or after treatment by the agitation leaching plant.

Geometallurgical Characterization and Automated Mineralogy

01 01 2016  For refractory gold ores in which gold occurs mainly as submicroscopic gold in sulfide minerals and is associated with carbonaceous matter in some deposits pretreatment is required before leaching making gold ore processing more challenging and ore characterization more important Classification of Gold Ores and Gold Ore

In addition operative management of the quality of gold

In addition operative management of the quality of gold ore grinding is carried out by changing the pro ductivity of ore based on a special adjustment of vi bration feeders changing the amount of water fed to mill washing trommels and pump sumps and timely loading of balls into mills and regular replacement of wear sands liners of hydrocyclones.
