In this vedio I will show you a very important information about the gold process extractions from ore and rocks /
Purification and deposition of gold from dust gold.
Copper, tin chloride and lead chromate complexes with gold.

Ores vary widely in chemical and physical characteristics, and a goodly proportion of precious metals are by-products of the mining and refining of other, less noble metals. Apart from gold, silver, platinum, mercury, and a very little copper, few metals are found in significant quantities as native metals. Methods of refining vary depending on the ore involved and the metallic value the operator is seeking. There is a definite crossover of technology from primary recovery to secondary recovery of precious metals. In fact, some processes of recovery and refining are exactly the same. Consider the treatment of an ore for extraction of gold by the so-called “barrel process.” In this process, the gold “values” are reduced to water-soluble gold chloride in a lead-lined rotating barrel (tumbler). The gold-bearing ore is roasted to eliminate any sulphides present. In this case, heat and oxygen serve as reagents. The sulphides are oxidized by being heated in the presence of oxygen, which produces sulphur dioxide. In any roasting operation, the by-products present an air-pollution problem and must be dealt with by precipitators or other means. In large operations, the sulphur dioxide is used to produce sulphuric acid and other sulphide chemicals. Of course, this decision depends on the cost and market

  17. Hocam mrb başarılar bu gibi taşlar ve cokta ceşitte meden olan taşlar 1 ton var bende ben bu taşı bu şekilde satamazmıyım yada bunu şekil alan yokmu niyemi taştaki medenleri cıkarmıyorum yav hocam cıkaramam ki hadi istesem de tek altın cıkar bilirim ya geriye kalan deyerli madenler ve minareller ne olacak hepsi cöp olacak işte ben bunun olmasını istemiyorum ve bende taş cok ceşit cevheri yüksek ve deyerli madeni yüksek bir taş bu şekil satın alan yokmu yani bu dünyada kilo bazında bir fiyattan sizce ben bunu satmak icin nasıl bir yol izlemeliyim tşk ler hocam

  28. Hello, did you add sulfuric acid? Was it mixed with distilled water? If so, what was the percentage? How long was it in the oven? What was the temperature? Thank you very much, dear friend.
