Establishing Gold Smelting Plant In Tanzania

Establishing Gold Smelting Plant In Tanzania

Gold Ore Formation Process

Earth’s total gold reserves of about 4.8 billion tons, and distributed in the Earth’s core is about 4.7 billion tons, 86 million tons mantle, and crust distributed to less than 100 million tons. More than 99 percent of the Earth’s gold into the core. This distribution of gold in the long-term evolution of the Earth’s formation. Earth’s crust formed early stages of development of its abundance of gold is high, and therefore, in general, to represent the early Archean greenstone belt composed of remnants of the earth’s crust, especially mafic and ultramafic volcanic assemblage, New Haven high degree of value in crustal rocks of various types may become gold deposits of the earliest “source bed.” In summary, gold abundance in the earth’s crust already low, and have an affinity for sulfur sexual nature of the pro-copper, iron pro-resistance, high melting point, etc., to form industrial deposits, gold to enrichment thousand times, to the formation of large mines, bonanza, gold will have enriched a few thousand, a few times, or even higher, showing its huge gold mine usually go through a long geological period, through a variety of sources, many times before superimposed mineralization may form.

Establishing Gold Smelting Plant In Tanzania

Tanzania gold resources abundant, widely distributed, many gold smelting methods. These include conventional smelting methods and new technologies. Smelting method, process improvements, and promote the development of Tanzanian gold industry. Currently Tanzania’s gold production in the world, has become one of the production Jinda Guo. According to this feature of gold ore, usually in the gold mining when, we need to Establishing Gold Smelting Plant.

Specific Gold Smelting Plant

Gold Smelting Plant usually contains four steps: pretreatment of ore, ore leaching, dissolved gold recovery, gold refining.

  • 1. Gold ore pretreatment. Gold ore pretreatment methods commonly divided into: roasting method, chemical oxidation, microbial oxidation, other pretreatment methods.
  • 2. Gold ore leaching. There are methods to extract gold from gold-bearing ore variety, which method to choose depends on the specific chemical composition of Tanzania gold ore, mineral composition, mode of occurrence of gold and product requirements.
  • 3. Dissolved gold recovery. Dissolved gold recovery generally use zinc replacement method and carbon adsorption, resin adsorption technology began to be used in industrial production.
  • 4. Gold refining. Gold refining methods are all-wet, which include electrolysis, aqua regia method, liquid chlorine method, chlorination, reduction of fire, wet a combined method of Fire.
