sulfide mineral | Definition, Examples, …
Sulfide minerals are the source of various precious metals, most notably gold, silver, and platinum. They also are the ore minerals of most metals used by industry, as for example antimony, bismuth, copper, lead, nickel, and zinc.
Sulfide Minerals - ThoughtCo
Galena forms in low- and medium-temperature ore veins, along with other sulfide minerals, carbonate minerals, and quartz. These can be found in igneous or sedimentary rocks. It often contains silver as an impurity, and silver is an important byproduct of the lead industry.
Sulfide Minerals - an overview | ScienceDirect Topics
Sulfide minerals are floated using mostly xanthates, dithiophosphates, and other thio compounds as collectors. The mineral–collector interactions and the selectivity in separating individual sulfide minerals from each other and from the rest of the nonsulfide particles can be controlled by a careful adjustment of pH and oxidizing, reducing, and complexing additives.

List Sulphide Minerals - Mineral Processing & …
The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. They are all heavy minerals and nearly all are of economic importance.
The Mineral Gallery - Sulfides Class
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.
