Separating Gold And Silver Dore Bars With Nitric Acid
Place the crucible in a furnace or oven. When using a muffle furnace, fire on high. Gold fires at 1950 degrees F. The gold should lay flat and look like honey with no lumps in it when it is ready. Quickly pour gold into a mold and let it set in the crucible until it has cooled. Remove the gold and clean with warm water and soap.

Gold Processing Plant
Mined gold-bearing ore containing gold and silver is extracted and purified through a processing plant. In this gold recovery plant, the precious metals are extracted from the ore through a series of steps including: crushing and grinding; addition of process water (forming a slurry); cyanide leaching; floatation and vortex separation (cyclones).

Gold Ore Roasting Plant
To achieve optimum gold recovery from the certain sulfide ore body, the ore must be finely ground to achieve proper oxidation and mineral separation. The ore is separated into stockpiles after it has been mined. These stockpiles are based on gold content, sulfide content, and carbonate content.

What Material is a Crucible Made of?
The use of crucibles can be traced back several years before the industrial revolution. And today, it is an essential item used either in laboratories for conducting high-temperature chemical reactions and analyses or in large manufacturing plants for melting and calcining metal and ore; they may be made of clay, graphite, porcelain, or a relatively infusible metal.

How to Assay Gold & Silver Ore
For example, the assay value of the fine pulp having been found to be $20.00, and the proportion of coarse gold to each assay ton of pulp 1 milligram or $20.67, then the total value per ton of ore in gold would be equal to $20.00 plus $20.67 or $40.67. Silver values fluctuate and may be figured at the ruling market price per ounce.

Gold Inquartation Process
The gold usually remains as a single piece if it weighs less than 0.1 mg., even if the proportion is only one part of gold to 40 or 50 parts of silver. If the ore is rich, the gold sometimes, though rarely, breaks up if hot acid is used, and invariably breaks up if the parting is begun with cold acid.
