The Copper King Mine was developed in 1881 by the Adams Copper Mining and Reduction Company, and in 2016, U.S. Gold Corp acquired 100% of the mineral lease to the property. While major mining operations ceased just prior to World War II, potentially mineable quantities of gold, copper, and other metals remain in the area.

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.

Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is. Much of the gold mined is actually from ...

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold ( 10 m) locked ...

Most of the silver produced today is a byproduct of mining copper, lead, and zinc. The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion of native silver or a silver mineral within the ore …

Prospecting from Orbit. Mining for ore isn’t what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.

Jul 20, 2021 Gold mines often have strip ratios of waste to ore that are large- often well over 5 tons of waste to 1 ton of ore. The Thacker Pass mine will have a waste to ore ratio that is 1.6 tons of waste to 1 ton of ore. This low waste to ore ratio will reduce the size of the pit correspondingly, since much of the material removed from the pit will be ore.

The present invention is a process to recover precious metals from sulfide ores. It involves chlorinating a mixture of an ore concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300 and 600 C. while stirring. The process converts precious metals in the elemental and sulfide forms into ...
