a brief review on blast-furnace slag and copper slag as fine .There are many studies reused granulate blast-furnace slag. (GBFS) and copper slag (CS) as a part of fine aggregate. Others recycled them as a part of binder material (after suitable grinding). In this article, an overview of the previous studies carried out on the use of GBFS and CS as a partial or complete replacement of.copper slag furnace slag copper,Minimization of Copper Losses in Copper Smelting Slag During .All experiments were carried out under conditions where three phases were present (copper–matte–slag), which is the condition typically prevailing in many slag-cleaning electric furnaces. The %Fe in the electric furnace matte was varied between 0.5 wt.% and 11 wt.%, and two different Fe/SiO2 ratios in the slag were used.

Recovery of copper from reverberatory furnace slag by flotation .

The recovery of copper from reverberatory furnace slag utilizing flotation has been studied. The effective factors such as particle size, pH, the amount and type of collector and additives, and flotation time were examined. The effect of cooling rate on flotation behavior of the slag was also studied. For an air-cooled slag at.

Textural, mineralogical and chemical characteristics of copper .

One furnace would produce 1 ton of copper per day as regulus assaying between 50% and 60% copper (Smalberger, 1975). These smelters were shut down in 1919 and never restarted. The smelters produced approximately 200 000 tons of slag. They were later transformed to sulphur burners of pyrrhotite concentrate for.
