Primary smelting and refining produces metals directly from ore concentrates, while secondary smelting and refining produces metals from scrap and process waste. Scrap includes bits and pieces of metal parts, bars, turnings, sheets and wire that are off specification or worn out but are capable of being recycled (see the article Metal reclamation in this chapter).

Anode, Copper anode. The positive side of the electrolytic cell. An anode is a rectangular plate of copper (or other metal) cast in a shape suitable for refining by an electrolytic process. Anomaly. Term applied to departure from normal or field characteristic, commonly used in
Roasting generally leaves more sulfur in the calcined product (15% in the case of the roaster at Mount Isa Mines) than a sinter plant leaves in the sintered product (about 7% in the case of the Electrolytic Refining and Smelting smelter).
Amalgamation Process of Gold Mineral Processing & Metallurgy
The use of direct amalgamation following stamps or primary mills and the use of barrel amalgamation for treating jig and corduroy concentrates. Precipitation of gold and silver on zinc dust or on zinc shavings is fully treated, from the clarification and de aeration of cyanide solutions to the cleanup and melting of
Process for electrolytic deposit of tin Robinson, Roger T.
A further advantage of vigorous mechanical agitation is that it lowers the cell voltage. The solution fed to the cell may contain the tin mainly in the stannous condition. Within the electrolytic cell the solution is subjected to electrolytic action to deposit the tin of the solution upon the cathode of the cell.
gold electrolytic refining aelabworld. electrolytic gold refining plant Working principles Electrolysis is a technological process that utilizes the electric energy generated from a current rectifier and from the technical features of acid solution. Get Price Gold parting .
Electrolytic Refining Electrolytic Refining of Gold. Electrolytic Refining of Gold The method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. Get Price. Get price
Electroplating is a process of coating a metal part with another metal, chromium or silver through electrolytic deposition. The reasons for plating metal parts sometimes are to make them resistant to corrosion, enhance their paint adhesiveness for decorative purposes. One of the different methods of plating metal parts is Rack plating.
The mechanical cleaning methods include grinding, brushing, steam or Forming and shaping will bring lubricants, oxides, and dust on the surface. Electrolytic alkaline cleaning provides a high level of agitation close to the . Some modern and advanced techniques can also be used on the heat treatment shop floor. Live Chat
Refining The gold is alloyed with silver and granulated, as in quartering. It is then boiled with concentrated sulphuric acid in cast iron boilers, silver, copper, lead, and other metals being converted into sulphates.
From copper and nickel processing. In nickel smelting, most of the cobalt is recovered during electrolytic refining of the nickel by precipitation from solution, usually as a cobaltic hydroxide. But even in nickel smelting, cobalt starts to oxidize before the nickel and can be recovered from the final converter slag.
Water Pollution Control In The Primary Nonferrous metals
Electrolytic Refining (13) The purpose of electrolytic refining is to produce a very high purity copper, and, at the same time, to separate from the copper and recover the valuable metal and metalloid impurities that are present in the "fire refined", or more properly, "anode furnace refined" copper.
Agitation of theelectrolyte is necessary to the successful practice of any electrolytic process for refining metals using solutions as electrolytes. I have not shown any mechanism for securing such agitation, as any of the well known methods may be employed.
