The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea. The first record of a reverberatory furnace is made by Jars, who states that copper-smelting was effected in reverberatory furnaces at …
Sep 21, 2012· The electric furnace or rotary slag-cleaning furnace are now generally used to perform this task, giving a level of copper in discard slag typically in the range of 0.55 wt.% and 1.3 wt.%, with most plants reporting copper losses in the discard slag in the range of 0.8–1.0 wt.%.
Consequently, wet-charged reverberatory furnaces have less copper in their matte product than calcine-charged furnaces, and they also have lower copper losses to slag. Gill quotes a copper in slag value of 0.23% for a wet-charged reverberatory furnace vs 0.37% for a calcine-charged furnace.
weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the material is typically very low. Granulated copper slag is more porous and, therefore, has lower specific gravity and higher absorption capacity than air-cooled copper slag. The granulated copper slag is made up of regularly shaped
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, fast-cutting action, considerably increasing production rates.
Typically, the majority of its composition is iron oxide and silicon dioxide, formed when molten slag is quenched in cold water. This cooling process fractures the slag into coarse and angular particles, making it an ideal blasting slag with optimal blasting properties. Advantages Of Ebonygrit – Copper Slag. Very high cleaning speed

Slag is less dense than matte, so it forms a layer that floats on top of the matte. Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag.
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.
