Toyo Smelter & Refinery | About Us
Mined ore which has a copper grade of less than 1% is turned into copper concentrate with a purity of about 30% at mine site and transported to the Toyo Smelter & Refinery. In addition to copper, copper concentrates contain about 30% each of iron and sulfur, and trace amounts of gold, silver and other precious metals, all of which are recovered.

balance sheet. The Operation comprises an open-pit mine feeding ore to a process plant with recovery of copper and precious metals into a saleable concentrate using conventional flotation technology. The concentrate contains approximately 23 per cent copper and up to 9 grams per tonne (g/t) of gold and 60g/t of silver.
FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES
This method of gold recovery is the preferred method for treating low-grade gold ores because of its low cost. Between 10-20% of the gold recovered each year from primary sources is extracted by this technique. The advantages of this process are: • Simplicity • Favorable capital • Favorable operating costs, which

SART for copper control in cyanide heap leaching
For proper heap design for cyanide leaching of copper-bearing gold ores, it is necessary to run long-term column tests (typically 60 to 180 days) at two or three different cyanide and/or pH levels. The relationships between gold-silver-copper recoveries, cyanide levels, and leach times will be different for each orebody. Since gold-copper types of
Crushing Plant Flowsheet & Design-Layout
In some copper concentrators, the mill feed is all passing 13MM(½"), using three stages of crushing and 14MM (9/16″) square openings on the closed circuit screens. It was felt by some that crushing to this fine size is only possible if the ore is friable and is relatively soft in comparison to the harder ores.
