Nov 11, 2013· Many chemically formed ore shoots yield good ore deposits. During vein formation, hot silica (quartzrich), 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.

Sulphideassociated Gold Sorting : TOMRA

Gold ores are frequently amenable to some degree of particle sorting when sulphide or quartz is associated with the gold. As regards the complex combination of sulphide associated with gold, the preconcentration of the ore in the early stages of the production process via sensorbased ore sorting is best achieved by Xraytransmission (XRT).
