  • GOLD AND SILVER

    Gold occurs mainly as native metal, alloyed with silver and/or other metals, and as tellurides. A naturally occurring alloy of gold and silver is known as electrum. Other gold minerals are rare. Gold is commonly associated with the sulfides of antimony, arsenic, copper, iron, and silver.3 B. Generalized Proc ess

  • Gold parting Wikipedia

    Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to

  • How to Separate Silver & Gold by Cementation

    Older processes explaining how to go about separating silver from gold by cementation were carried on practically in two ways, the first by heating gold for a long time with a mixture which evolved nitric acid on heating, and an absorbent into which any fusible salts ran; the mixture in the second method contained common salt as an essential ingredient, and some material which would assist in

  • Parting metallurgy Britannica

    Parting, in metallurgy, the separation of gold and silver by stone or electrochemical means. Gold and silver are often extracted together from the same ores or recovered as by-products from the extraction of other metals. A solid mixture of the two, known as bullion, or doré, can be parted by boiling in nitric acid.The silver is dissolved as silver nitrate, leaving a residue of gold that

  • Separating Platinum from Gold During the Early Eighteenth

  • Gold Mining Epc Gold Silver Separation Process Efficient

    We have Gold Mining Epc Gold Silver Separation Process Efficient,Separation efficiency between precious metals and slag is evaluated by taken slag samples and perform assays for gold and silver. the performance depends on the charge properties, gold and silver content and fluxes efficiency. during the smelting process, any residual mercury contained in the concentrate will be eliminated in the

  • metallurgy How were silver and gold separated using the

    One can try this gold on a touchstone or otherwise ; and if it is found insufficiently pure, submit it a second time to the process. The vitriolic acid of the stone and of the calcined vitriol, releases the acid from the common salt during this cementation ; and this last one dissolves the silver alloyed to the gold, and seperates it by this mean.
