Gold Basin's post office was established September 20, 1890 and discontinued June 15, 1907. A five stamp mill was about all Gold Basin amounted to. There were many mines in the area but none that were really big producers. Gold Basin was located 30 miles from the nearest water and shipping lines, so fuel for the mill and water were scarce.
Gold ore can resemble quartz with spotty areas of gold. According to the Environmental Protection Agency, gold is commonly mixed (alloyed) with silver and other metals. The ore may, therefore, contain sulfides like arsenic, copper, iron, and silver. The ore does not commonly have visible shiny gold on the surface.
Sometimes the ore is very deep, which is often the case with diamonds or gold ore. In these cases mine shafts go vertically down and side tunnels make it possible for the miners and equipment to reach the ore. A structure called the headgear is constructed above the shaft and controls the lift system into the vertical shaft.
gold ore from the Oro Blanco district in Santa Cruz County, Arizona, about 70 miles southwest of Tucson. Treatment tests have never been made on this material to the writer's knowl-edge. The object in selecting this subject was to study gold-milling methods and incidently to determine, if possible, the
Gold ores are classified "free-milling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an …

The amount of iron oxide copper gold ore is about 10 million to 4 billion tons. IOCG ore contains copper with a grade of 0.2% to 5% and gold with a content of 0.1 to 1.41 grams per ton. Iron oxide copper gold ore tends to be conical on the edge of granite, or appears as long banded breccia or massive iron oxide ore in faults or shears.
