My expertise is mostly in hard rock mining and the recovery of metals, including the crushing and grinding of the ore. I've also spent a few years in assay labs, and running start-up pilot plants. My current gold project is a pilot plant with a maximum capacity of 300 TPD, and we will be using some form of a mill to fine grind the ore.

Endogenetic gold ores include vein and lode deposits of elemental gold in quartzite or mixtures of quartzite and various iron sulfide minerals, particularly pyrite (FeS 2) and pyrrhotite (Fe 1-x S). When present in sulfide ore bodies, the gold, although still elemental in form, is so finely disseminated that concentration by methods such as those applied to alluvial gold is …

In many cases, the discovery of an ore-rich source rock happened entirely by chance. Many people found gold known as placer deposits in rivers, where the ore was washed out from hard rock deposits due to wind and water erosion (See Fig. 1.) ("Placer deposit", 2010). Stream placers, also known as alluvial placers, are the best-

The ores containing Native Gold erode due to weathering, and as the encasing rock breaks down, it produces Elluvial Placer Deposits (Bench Placer). These deposits form on the slopes of hillsides where a depression or wide level spot occurs downslope of the eroding In Situ (In Place) Hard Rock Deposit from which the gold is eroding from.
