Get Pricemetals in contexts other than silver smelting. Agricola mentions borax (p. 247) for the assay of lead Biringuccio included it in his general list of fluxes (p. 143). Considering that borax was a wellknown flux in period, I think it's reasonable that it was used in the fusion step for smelting silver.
Get PriceA refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach solution to form a complex with the gold. Organic carbon present in gold ore may adsorb dissolved goldcyanide complexes in much the same way as activated carbon.

Get PriceJul 10, 2017· The metal containing solid, such as concentrate, ore, residue, or slag, often undergoes size reduction via crushing and grinding prior to leaching. One example of a leaching process that uses vat leaching is gold cyanidation, the process of extracting gold from lowgrade ores.
Get PriceThe multiple forms of silver make cyanide leaching more complex than gold leaching. Intricate leaching chemistry kinetics to liberate silver from unwanted material must be specifically tailored to each new ore deposit. Gekko recommend complete laboratory testwork be performed before initiating the design of an effective silver recovery plant.
Get PriceZinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, iron, because in contrast, zinc has a low boiling temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...
Get PriceSilver is a precious metal located throughout the world in geological deposits. Colorado's state nickname is the "Silver State" due to the large deposits of silver ore found there. Silver is extracted from the ore by a smelting or leaching procedure. Here's how to identify silver ore.
Get PriceAny silver present in the ore, will also be leached in the cyanide solution, and will be present in the dore bar, as well. Most mines do not have the refining capacity to separate the silver from the gold and the bars are sent to a commercial refinery for producing the % gold and silver ingots that are sold on the commercial gold market.
Get PriceYour options are pretty limited for this application as a silver/zinc ore likely does not have free silver in it, the silver is generally in the sphalerite matrix and is recovered by producing a zinc concentrate and smelting it. You may try gravity separation to see if there is free silver (just pan some of the ore).
