The SuperbMelt gold smelter is designed with the most powerful IGBT induction technology available in the market for 1kg to 50kg gold melting. This great feature also gives this machine the flexibility to melt different kinds of metals. With the gold smelter higher melting temperatures is very realistic.

The addition of scrap iron to smelt mixes is a useful technique to smallscale operators experimenting with smelting techniques on goldsilver ores. It could also be used with small lots of sulfide concentrates. On the other hand, there are alternatives for processing sulfide ores. The way the Spanish did it, the old "patio" process is ...
Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Process Description24
for its minerals. It is important to note that our gold/copper/silver concentrates are already a highly processed and beneficiated product. Whilst the smelters do charge to process our concentrate, on average for the contract terms that we have agreed with the overseas smelters, we receive 97% of the total value of gold, silver and copper.

The Calciner allows the Smelter to treat complex endoflife materials such as rechargeable batteries, plating sludges and catalysts in an environmentally sound manner. The concentrate is fed to roasters where sulphur is removed as SO 2 gas and sent to the sulphuric acid plant for treatment. The roaster product (calcine) is fed to the electric ...
History. The smelting of gold began sometime around 6000 3000 BC. According to one source the technique began to be in use in Mesopotamia or Syria. In ancient Greece, Heraclitus wrote on the subject. According to de Lecerda and Salomons (1997) mercury was first in use for extraction at about 1000 BC, according to Meech and others (1998), mercury was used in obtaining gold until the latter ...

Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractorylined furnace of either the hearth or ...
Concentrates are usually specific to particular smelters. Thus a lead smelter or a zinc smelter could not smelt a copper concentrate (the converse is also true). In fact any copper in a lead or zinc concentrate is generally problematic in the smelting/refining processes and would most likely incur a penalty charge (see more on penalties below).

The value of the free copper, gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate, LME copper price and LMBA gold and silver price. In this example the recovery rate for a copper smelter is %. The value of free gold and silver is normally greater than the value of the free metal for copper.

Gold can be present in the copper concentrate as free gold particles or in solid solution in the chalcopyrite itself. For example, at Norilsk, the chalcopyrite has been measured to contain between 1 and 7 g/t of gold in solid solution (Sluzhenkin and Mikhov, 2003). During the smelting operation, gold, silver, and other PMs remain closely ...
