Copper Slag is an aggressive abrasive frequently used in new steel and steel maintenance applications. Its bulk density and angular shape give it an aggressiveness that provides clean, fastcutting action, considerably increasing production rates.
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of % to blister. This technological procedure is divided into two phases, first slow cooling of slag on the air for 24 hours, and then accelerated cooling with water for 48 hours.
Copper recovery from primary smelter slag consists of the removal of mechanically entrained copper matte and metallic copper inclusions, formed during reduction of dissolved cuprous oxide. After the relatively fast separation of larger matte inclusions the system can be seen as a suspension of liquid matte and liquid metallic copper in liquid slag.

Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state.
Leveraging a Resource Recovery Opportunity. Used copper slag is one of the largest byproducts of shipyard operations. The industry generates an estimated 300,000 tonnes of copper slag a year. Conventional methods of disposal relied heavily on landfill dumping which contributed negatively to the environmental landscape of landscarce Singapore.
Smelting history goes back at least 6 000 years to the copper smelters of the Timna valley near Eilat in Israel. Copper is the world's oldest metal and was used more than 5 000 years ago for water plumbing in the Pyramid of Cheops in Egypt. The Egyptians obtained their copper from Israel and from Cyprus.

A fundamental study on the molybdenum recovery from the copper smelting slag by slow cooling. In European Metallurgical Conference, EMC 2013 (pp. 689702) A fundamental study on the molybdenum recovery from the copper smelting slag by slow cooling.
Copper Anode Slime Recovery. The chloride leaching solution of lead anode slime is used to recover Cu/ Bi/Sb separately. As a conclusion, it is widely acknowledged that the anode slime is complex in content but of high value, and the tendency to utilize the anode slime is to shorten recovery process and production period, reduce circulating loss and increase recovery rate.
Metal Recovery; TMS's patentpending KWIK Cooling process reduces the required method of cooling nonferrous material from 60 hours to 12 hours by using its proprietary cooling vessels (CV). Once filled with slag, the CVs are placed in specifically designed cooling stations. After 12 hours, the CV is tipped and the matte and slag are separated.
