GOLD RUSH

Jan 06, 2020Many chemically formed ore shoots yield good ore deposits. During vein formation, hot silica (quartz-rich), hydrothermal acidic fluids react with rocks with favorable chemistry; particularly rocks with calcium carbonate (limestone, dolomite). Thus, following a vein that cuts through limestone could lead prospectors to find skarns, replacement deposits, etc for gold and other valuable minerals.

Carbon Adsorption In Recovery Of Gold

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton. If the ore is a high grade, it may be feasible to
