At the mine site, gold is melted along with the silver into what are called doré bullion bars. These also contain a little bit of other metals like copper. If the doré bars have a large amount of silver, that is recovered first in a process called electro-refining. Basically, the doré bars are submersed in containers of silver nitrate solution and become the anode in an electrolytic cell. As an electric charge is applied, the silver is purified as it dissolves from the anode and deposits on the cathode. In the silver electro-refining process, the gold is left behind as the silver dissolves. The gold basically falls to the bottom of the anode. This is known as gold mud. It is collected, washed, and dried. It is then refined in a process called chlorination. Basically, chlorine gas is introduced into the crucible as the gold is melted into ingots. The gold is separated from the remaining base metals and is poured into granules or bars for commercial sale
All gold arriving at a refinery is evaluated for gold content which must be agreed upon with the customer before it is released for refining. This can be a simple melt, sample and assay procedure for shipments in metal-bar form. Alternatively, it can be a complex mix of burning, drying, grinding, screening, blending and sampling for low-grade scrap and floor sweepings. Whatever the material, proper evaluation is key to arriving at a settlement that is fair to both customer and refiner. Once agreement has been reached, the material can be released for refining. The refining process selected depends on the form and metal content of the shipment.
no how would you uncrack them? on the other hand until they actually pop - well lets just say y ou can ride them long after they look bad wle
not possible to repair but there are cracks that are not of concern and others that are dangerous.
