In the Balkhash Copper Smelting Plant (BMZ) CS flotation tests have been conducted, cooled by a normal method (in ponds for one day) and slowly (in slag basins for ≈ 34 days). Slag refinement and its treatment were conducted by the SUMZ scheme.
The results of analyzing the particle size and shape of copper slag samples after heat treatment of the samples showed that thermal treatment promoted copper slag grain size reduction (Fig. 2): the number of large particles (210 microns and more) was reduced twofold, and the number of particles down to 176 microns was amount of grains within the interval from 176 to 210 μm ...
Altonorte Slag Flotation Plant Milling And Flotation Of Slow Cooled Copper Slag. Altonorte Copper Smelting Plant Wastewater, Chile In March 2003 the Altonorte copper smelting plant near Antofagasta, in northern Chile, completed a 170 million expansion that started in expansion, study consisted of the physical, chemical, and mineralogical ...
Long term practice has proved that copper in slag can crystallize quickly in the process of natural slow cooling, which can realize the formation and aggregation growth of copper crystals, so as to facilitate subsequent grinding and flotation. Consequently, slow cooling technology is more instrumental in the recovery and utilization of copper ...
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of % to blister.
A kind of chilling vessel slag and the method for slow cooling electroslag bulk flotation, the most respectively chilling vessel slag is sorted out with the composition brass in slow cooling electroslag and white metal, after dispensing, coarse crushing processes according to a certain percentage, carry out crushing and screening again, the Ore that granularity is qualified enters I section ...

For this purpose, it uses existing flotation line (mill section B) for copper slag processing in the Bor flotation plant. ... The process of treating smelting slag includes: slow cooling, crushing, grinding and flotation. After the cooling process is obtained by copper slag with maximum grain size 150 mm, wherein an average copper content of 2 ...
of nonstationary slag cooling and experimentally tested the properties of slowcooling slags. They verified that, under slowcooling conditions, the generation of larger copper and copper sulfide particles was promoted, and thereby the particles could be better collected in the subsequent flotation to reduce copper losses in the waste slag.

Another aspect that can affect both the milling and flotation of CS is the cooling behavior of the slag. ... Recovery of copper from slow cooled ausmelt furnace slag by floatation. Characterization of Minerals, Metals, and Materials 2015, 621628. / ...
copper grade of 16,11% and copper recovery of 69,90% was achieved. The copper grade on tailings was only 0,2%. Another aspect that can affect both the milling and flotation of CS is the cooling behavior of the slag. Several researchers have reported that slow cooling of the slag can lead to an improvement in copper recovery because of the ...
The beneficiation of copper slag employing gravity concentration and froth flotation, with particular emphasis on different collector systems, has been reviewed thoroughly. Further, the reported pyro and hydrometallurgical processing routes have been deliberated.
There are two ways of cooling copper slag: slow cooling and water quenching. Different cooling speed will determine the particle size and mineral composition of copper minerals in copper slag. ... Then through grinding and flotation, the copper content in the copper slag was reduced to %.
These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard smelter objective is to process wet concentrate to produce crushed slow cooled sulphur deficient nickel copper matte rich in platinum group metals gangue from the ...
Generally, slow cooling slags are more beneficial for better recovery of copper by flotation. A slow cooling rate of the molten copper slag can minimise the effect of viscosity on the mass transfer of diffusion and grain growth of matte copper (or metallic copper), and further help in the subsequent fine grinding and flotation stages of copper ...
After testing of the experimentally gained samples of slowly cooled slag it was found that this technological procedure gives the best results in promoting growth or coagulation of dispersed...
Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. ... the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. ... Several researchers of discarded slags has motivated the reprocessing of this have reported that slow cooling of the slag ...
By simultaneous adding old flotation tailings in the ball mill at the rate of 9%, it is possible to increase copper recovery for about 20%. ... recovery copper from slowcooled CS by flotation ...
slowcooling conditions, the generation of larger copper and copper sulfide particles was promoted, and thereby the particles could be better collected in the subsequent flotation to reduce copper losses in the waste slag. In addition to testing the cooling time and controlling the cooling rate, some researchers have even considered using slag ...
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.
