Carlin Type Gold Deposit Mineral Processing & Metallurgy

Historically Carlin Type Gold Deposit are big elephants but until recently they were largely known to occur only in the limited hunting ground of Northern Nevada that limitation is now beginning to change. How Carlin gold deposits fit into the overall scheme of things. The early fluids contain little gold but late in the process there is a

Geology of Gold Mineralization & How Gold Deposits are Formed

The Geology Of Gold. In the past, low grade disseminated gold deposits have become increasingly important. More than 75 such deposits have been found in the Western States, mostly in Nevada. Deposits of this type are mined for the predominant metals, but the gold is also recovered as a byproduct during processing of the ore. Most

TECHNOLOGY FOR PROCESSING OF REFRACTORY GOLD

disseminated gold from the flotation concentrate resulted from processing of a refractory ore of one of Russian gold deposits. Concentrate description Gold grade of the head flotation concentrate was 29.6 g/t. The concentrate size was 80% 80 um. Mineral composition of the concentrate comprises 17% of rock forming minerals, 59% of pyrite and 24%

Basic Gold Prospecting & Exploration Methods

The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their interest for gold is the most valuable tool for exploring new deposits. Gold is a very widely disseminated throughout nature and may be found in any geological formation from the oldest rocks to the

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Disseminated Ore Mining Fundamentals

Gold, copper, molybdenum, and several other valuable metals have been discovered and mined from disseminated deposits. The Carlin Trend in Nevada, USA, is a very good example of disseminated ore. In Australia, gold occurs in the following

Carlintype gold deposit

The gold mineralization is very finely disseminated "invisible gold". Carlintype gold deposits are sediment hosted disseminated gold deposits. These deposits are characterized by invisible (typically microscopic and/or dissolved) gold in pyrite and arsenopyrite .
