How is Silver processed – Silver is most conductive and reflective metal on our earth. People have been making silver jewelry and other objects since about 4000 BC. Silver is not only used in jewelry. As 80% of silver is mined for industrial purposes. It is used mostly in electronic components and in construction as an insulation coating on glass. The mining company produces silver bars

Normal mining costs are about 50% of the income derived. Apache's reclamation costs are estimated to about 3% of income. Old time ore processing only looking for gold left behind vast treasures of waste tailings piled in above ground dumping sites. Old separation technology missed tremendous amounts of gold. Vast fortunes of precious metals and

SILVER MINING VIDEOS. Silver- a soft, white lustrous transition metal that possesses the highest electrical conductivity of any element, most silver is produced as a spin-off of copper, gold, lead, and zinc refining. The metal emerges naturally in its untainted, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. This long

Mining and concentrating. Silver-bearing ores are mined by open-pit or underground methods and then are crushed and ground. Since virtually all the ores are sulfides, they are amenable to flotation separation, by which a 30- to 40-fold concentration of mineral values is usually achieved. Of the three major types of mineralization, lead concentrates contain the most silver and zinc concentrates the least.

This silver is mined by drilling the silver out of the ore until the vein of silver stops, meaning there is no more silver to be mined. Silver is also found during the process of extracting copper, lead, zinc and gold as well as in alluvial (rich soil) beds and riverbeds. Since mining silver usually makes a lot of noise, mining sites are usually located far from a city.

23.01.2012· Step #6 – Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes

Mining in Europe has a very long history. Examples include the silver mines of Laurium, which helped support the Greek city state of Athens.Although they had over 20,000 slaves working them, their technology was essentially identical to their Bronze Age predecessors. At other mines, such as on the island of Thassos, marble was quarried by the Parians after they arrived in the 7th century BC.

The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead. The local variety of Galenite is silver-bearing and is known as Argentiferous Galenite (formula (Pb.Ag)S ) and the lead obtained from this ore contains just a small percentage of silver - from 0.8% up

Why Mining Silver Is Different than Other Rare Metals. For thousands of years, mining silver was not much different than mining copper or zinc or gold or iron. Past prospectors and exploration companies sought out silver deposits, set up mines to pull the silver out of the earth, and then shipped it to a refinery. Gold and copper and zinc and iron still get mined this way. By the 20th century

The process is attributed to a mining specialist – Bartolomé de Medina who was the first to use a silver amalgamation with mercury to extract silver. De Medina' s technique involved mixing the ore with mercury and strong brine. This formed a mercury silver amalgam from which semi-pure silver could be obtained by distilling off the mercury.
