Gold Refining Equipment
Gold has been prospected and mined since ancient times as it is one of the most precious metals and has been used as currency and as the main item for barter. Gold has been regarded as wealth in almost all the cultures and its value has been determined by its purity. Gold occurs in veins and the ore is mined and then has to be processed with gold refining equipment to get different levels of purity. The gold in the ore is mixed with silver, quartz and other sulfide minerals. With gold refining equipment you can remove these substances and get the level of purity which you want.
Since ancient times different refining processes have been used to purify gold and some of these methods are still in use today. As per the process, the gold refining equipment will also be different. There are many companies today who make gold refining equipment having various capacities which are suitable for different refiners.
One of the popular process of refining gold is the Miller process and the gold refining equipment is an induction furnace. In this process Chlorine gas is to be introduced so that chlorides are formed with the contaminants. Silver, nickel, copper and other metals can be removed along with atmospheric elements. The chlorides which are formed will float on top of the molten gold in the form of slag. This slag is manually removed by the gold processing equipment into a crucible used for de-golding. If there is any gold still present in the slag it will settle at the bottom and solidify. Then the top molten chloride is poured off into other crucibles. The gold processing equipment has a ceramic filter through which the molten gold is poured into an anode mould. This anode mould is actually the granulation equipment in which there is a system of treating the granulation water before it gets discharged.
The gold refining equipment is built in such a way that gold is extracted to the maximum and none is wasted in the process. Even the fumes of the metal chlorides are passed through chambers for filtration, which will maximize the recovery of gold and cleans the air which will be given off at the exhaust. The whole process takes about 2 to 4 hours and will depend on the volume of input and the content of gold. Gold refining equipments are built to maximise recovery and minimise the dangers caused by the by-products and slags.
It is fairly obvious what the job of a cook will entail, but if you have skills in this area would you consider working on an oil rig to put them to the test? It certainly provides an altogether different environment from where many other cooks work, and yet it is...
