[VIDEO] The History and Process of Silver Mining
The process of mining for silver is broken down into three steps: removing ore from the earth, breaking it down and then flushing the silver from ore. The first step involves drilling holes in the silver-rich areas geologists have previously pinpointed and then inserting dynamite sticks. After the blast, miners haul the chunks of rock calledGroudev et al. (1999) used solutions that contained amino acids of microbial origin and thiosulphate to leach the gold and silver from oxide ores that contained 3.5 g/t of gold and 14 g/t of silver. First, an alkaline solution (pH 10–10.5) was irrigated on the top of the heap to stabilize the pH.Gold leaching from ores using biogenic lixiviants A review

Processing. At the surface, the ore is subjected to additional crushing and fine grinding. A flotation process is used to separate the silver-bearing galena and tetrahedrite from other ore minerals and waste rock particles (tailings) to form mineral concentrates. Development of the flotation process occurred in the early days of mining Silver, in the metallic state, is commonly associated with gold, copper, lead, and zinc (Ayres and Peiró, 2013). The primary source of gold and silver is surface mining, which requires extensive blasting. Further processing starts with the milling operation and concentrating the ore through the beneficiation process.Impact analysis of goldsilver refining processes through life

Metals Free Full-Text A Review of the Cyanidation
Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has Table 6.5 shows the average grade of gold ores at Barrick operations. In 2016, the average grade of gold at major mines owned by Barrick was lower than 4 g/ton. There are many gold miners, including Barrick, that are processing gold ores having less than 1 g/ton of gold. One troy ounce of gold is equal to 31.10 g.Waste Management in the Gold and Silver Industry

Silver recovery aqueous techniques from diverse sources
Leaching represents the first step of the hydrometallurgical route and the recovery of silver by different techniques including cementation, chemical precipitation, adsorption, bio-sorption, electro-coagulation, electro-winning, ionexchange and solvent-extraction, etc. are very important cost-effective silver recovery and extraction processA somewhat similar experience occurred at the Mt Gibson gold plant, which was designed to process laterite ore, which overlaid deeper mixed oxide–sulfide ore. The ore contained about 500 g/t cyanide-soluble copper, some of which was associated with sulfide mineralization and which occurred within highly weathered clay minerals.Gold-Copper Ores ScienceDirect
