Copper Slag Copper slag, which is produced during pyrometallurgical production of copper, contains a significant amount of Cu together with trace amounts of other heavy metals. According to Gorai et al. (2003), about 2,2 tons of copper slag is generated for every ton of copper production. Approximately 24,6 million tons
Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.

The present invention relates generally to a process for recovering copper and/or other metal values from a metal-bearing ore, concentrate, or other metal-bearing material using pressure leaching and direct electrowinning. More particularly, the present invention relates to a substantially acid-autogenous process for recovering copper from chalcopyrite-containing …

the copper ore concentrate is mixed and nodulized with a carbonaceous fuel and a flux to produce autogenous smelting nodules. the nodules are smelted autogenously and the resulting molten matte and slag are converted to molten blister copper and converter slag by blowing the heated nodules, matte and slag with an oxidizing gas in a converter.
The process is a continuous, multi-step process which produces blister copper from concentrates in three interconnecting furnaces. Concentrate and oxygen-enriched air (30-35% O2) enter the smelting furnace through vertical lances and are smelted to produce a matte of 65% to 69% Cu and low-copper slag. Fuel must be burned to satisfy the heat ...
In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50-percent copper matte. The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at one end of the furnace.
Aspects of energy reduction by autogenous copper production in the copper smelting plant Bor. ... (4, 6), grinding the slag from the smelting process (4, 7, 8) and grinding the slag from the conversion process (4, 5). The energy consumption for oxygen production to enrich the air is, in all cases where it is used, ...
Ghafari et al. found that, as the silica fume was fully replaced by fly ash or slag, the 28-day autogenous shrinkages of UHPC were reduced by approximately 15%. It is noteworthy that the ability of rice husk ash to mitigate the autogenous shrinkage is stronger than other alternatives due to the porous structure which provides an internal curing ...
Then wet grinding in semi-autogenous rod or autogenous ball mills takes place. Size classification takes is performed in cyclones. In the next step of beneficiation, valuable minerals and gangue are separated by froth flotation of the ore pulp, which exploits the different surface properties of the sulfidic copper ore and the gangue [46].
combining functions of charge melting, slag and matte separation, matte accumulation in quantity needed for its further processing; − KFP process is a white matte and high-basic self-grinding slags with further decoppering are the most progressive technology in world practice of sulphide raw material autogenous smelting.
The other way for size reduction of steel slag is one-stage dry autogenous grinding. One advantage is that one autogenous grinding machine can replace several crushers in multi-crushing so that its operation is simple. Moreover, the metallic iron product discharged from the grinding machine contains Fe as high as 80%.
Processing facilities consist of a copper concentrator, hydrometallurgical plant, copper smelter, sulphuric acid plant, copper and gold/silver refineries. Recent expansions included a Svedala autogenous mill, additions to the flotation sections, two counter-current decantation thickeners, an electric slag-cleaning furnace, a new anode furnace ...

The Mount Isa Copper Concentrator grinding circuit currently consists of two 32' x 16' semi-autogenous (SAG) mills, each powered by two 3.2 MW motors, followed by two 16'6" x 20' ball ...
Total autogenous shrinkage ranged between 100 and 350 με. The highest shrinkage occurred in concretes with low w/b ratio containing SCMs and larger aggregate particles. The presence of silica fume and GGBS increased autogenous shrinkage by a factor of ~1.3 and ~ 1.9 respectively relative to the CEM I systems.
In terms of phase composition and structure, this microstructure is close to that of typical slag obtained by the same way in the process of autogenous smelting at the other copper- …
Single particle experiments were carried out in the present study. An industrial copper matte powder, containing 68.04 wt.% Cu, 0.50 wt.% Se and 0.08 wt.% Te was taken as the starting material. Se and Te phase assemblies and distribution behaviors were systematically investigated in the air atmosphere. It was found that Se reported to blister copper, matte, and …

The physical properties of copper slag are given in Table 2.As seen, the density of copper slag varies between 3.16 and 3.87 g/cm 3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 g/cm 3 that means copper slag is denser than ordinary natural aggregates. In general, water absorption of copper slag is very low.
The recovery of copper by floatation from slow cooled Ausmelt furnace slag was studied in this paper. The phases and composition of the slow cooled slag were analyzed. The factors which affected the copper recovery efficiency such as grinding fineness, pH value of flotation medium, different collectors and floating process were investigated.
