520 |a"The term "complex sulphide ores" generally refers to the relatively finegrained, pyritic, polymetallic base-metal ores of volcanogenic origin. The metals of economic value in these ores are copper, zinc, lead, silver, gold, tin, cadmium, indium, selenium, and tellurium. The metals occur principally as constituents of the minerals chalcopyrite, sphalerite, galena, tetrahedrite, cassiterite, electrum, and many sulphosalts. The metal-bearing minerals are recovered by flotation in copper, lead, and zinc concentrates, which are then smelted and refined to recover the metals. Process mineralogy provides fundamental information for designing mineral beneficiation, extraction metallurgy, pyrometallurgy, and other plants for treating the ore, concentrates, and other products. Recent developments of equipment such as the automatic SEM-IPS-IAS image analysis system have made it possible to perform rapid quantitative analysis of mineralogical characteristics that affect processing. Previously, these analyses could only be determined qualitatively or not at all. The analyses have provided a better understanding of the behaviour of minerals and phases during processing, leading to improved metal recoveries at processing plants"--Abstract, p. i.
