What is a Copper Slag? (with pictures) wiseGEEK

May 25, 2020· Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.

Minimization of Copper Losses in Copper Smelting Slag

Nov 01, 2012· Such conditions include operating the electric furnace at metallic copper saturation, maintaining the %Fe in the electric furnace matte between 6 wt.% and 9 wt.%, not exceeding a slag temperature of 1250°C, and controlling the Fe/SiO 2 ratio in the smelting furnace slag at ≤1.5. In addition, magnetite reduction needs to be performed

Effect of Cooling Rate and Slag Modification on the Copper

Jul 31, 2020· The amount of copper flash smelting slag has increased during the recent years along with an increasing slag-to-metal ratio. During slag tapping, some copper sulfide is mechanically entrained. As a result, it is necessary to recover copper matte from the slag by suitable methods. At present, the most common way is slow, controlled cooling in a transfer ladle.

MECHANISM OF BUILDUP FORMATION IN AN ELECTRIC

The copper slag cleaning in an electric furnace is based on slag reduction and settling of copper matte inclusions. Copper recovery depends on the slag temperature, degree of magnetite reduction and slag residence time. The formation of solid buildup on the furnace hearth leads to the decrease of furnace volume and slag residence time, affecting

Recovery of Copper from Reverberatory Copper Slag and

possible option. The copper slag contains a high content of silica and iron. The solution final pH is the most important factor affecting the removal of iron and silica from the leach solution and the overall metal recovery. Fe removal from the leaching of copper slag is done by the formation of a metal hydroxide.

Recovery of cobalt, nickel, and copper from slags, using

Nickel-copper furnace and converter slag -200 kVA. During 1995, a campaign was undertaken on the 200 kVA furnace with the intention of combining furnace slag with the converter slag previously treated. When treating furnace slag containing 0.22% Co on its own, the maximum cobalt recovery that could be obtained was 66%, with a cobalt value of 0

ISASMELT TM SLAG CHEMISTRY AND COPPER LOSSES IN THE

Each furnace is rotated by a hydraulic drive linked to the furnace by a chain. By rotat-ing the furnace one way or the other, the operator can either pour the slag into the hauler pot or pour matte into a pot in the aisle. The maximum rate of slag skimming is control-led to minimize the copper content of the slag.
