The PCA of geochemical and mineral abundance data for ores from gold deposits within the Abitibi of Canada provides useful information on the mineralization and alteration within these deposits. The most critical first principal components (PC E 1 and PC M 1) can efficiently discriminate between mineralized and barren or altered rocks. The PCA ...

A high grade gold mine was observing large discrepancies between production samples from drill cuttings and the original block model. Further, there was large variation among grab samples from the same areas. The mine needed to know the true grades in order to define ore and waste as well as reconcile the block model data.

Recognizing Gold Ore: What to Look For. Gold mixes with different minerals, which will affect the look of the ore. If you are looking for larger chunks of gold, stick to lode deposits, where plate tectonic activity has brought gold to the surface. Lode deposits usually form gold in larger veins, so it should be easier to see.

Not all refractory gold ores give a large recovery improvement after fine milling. Gold locked in arsenopyrite for example does not achieve the same gold recovery as gold disseminated in pyrite due to the smaller gold particle size of the locked gold (Figure 5). Figure 5.

Abstract: Gold ores associated with carbonaceous matter present several difficulties in their extraction due to the ability of this matter to adsorb the aurocyanide complex from gold pregnant solutions, resulting in low extractions by direct cyanidation. This phenomenon is known as preg-robbing. In the present work, a process to effectively recover Au from a highly …
