The copper mining process. KAZ Minerals operates six producing mines. The three mines in East Region are underground while the Bozshakol, Aktogay and Bozymchak mines are open pit. The mines generally contain sulphide ores and by-products that vary in quantities and proportions between mines. The main by-products are zinc, silver, gold and ...
Published 2017. Materials Science. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD.
The copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities.
All the other species entering the slag concentrator was given the recovery of 6%. The BBR-BCC process was an exception, because otherwise the discharge slag copper would have been too high with these parameters. Thus, the recovery was increased to 93% for all the copper compounds and 20% for the others, resulting in slag with 0.6% …
The simulation results predicted that the copper losses to slag would be 7.9, 20.4 and 7.0% of input copper for the un-fluxed, iron oxide flux and the lime and silica fluxing scenario respectively.

Converter slag assaying 3.7 per cent Cu is produced by Mount Isa copper smelter at a rate of up to 180 000 tonnes per annum.Priority is given to the processing of ore, however concentrator capacity periodically exceeds that of the mine and the opportunity is taken to treat converter slag. It is processed in batch campaigns, typically through the Copper …

This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests. ... industrial copper slag flotation campaigns, it was concluded that it is possible to ...
Vertical top-blown lance is used to inject oxygen enriched (up to 80% with 150 kPa(g)) air direct into melt. The mixture reacts in the molten bath to form a matte and slag emulsion, which ...
The purpose of the slag concentrator is to recover copper from the slag produced in the copper smelter and to return it to the copper production cycle as high-quality slag …

Osvaldo Pavez1, Pablo Herrera2, Miguel González3, and Oscar Rivera4. ABSTRACT. Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests.
After solidification and cooling, the slag is crushed, ground and treated at the slag concentrator. Copper bearing minerals are separated in the flotation cells. The slag concentrate containing the recovered metals is filtered and recycled back to the copper flash furnace. The remaining final slag tailings are discarded from the flotation cells ...
The ore mill processes ore from the mine by means of the following main concentrator areas: North/South Concentrators, Concentrator #3, and Concentrator #4. Processing design capacity (nameplate capacity) is described in brief (in 000 ton metric tons per day): ... Flotation is a separation process to produce copper-gold concentrate. Concentrate ...
Boliden Harjavalta has chosen Outotec's SMD grinding mills to improve the capacity of its slag concentrator, in Finland, the mining OEM says. Boliden Harjavalta produces high-quality metals for European industrial customers, churning out 120,000 t of copper and 26,000 t of nickel in 2019. The purpose of the slag concentrator is to ...
Three copper smelters (San Manuel, White Pine, and Garfield) process all their smelter slag either in a conventional ore concentrator or in a stand-alone slag concentrator. The slag tailings from these operations are co-managed at on-site tailings piles with the tailings from ore beneficiation. Slag tailings ponds range from 142 to 2,270 ...
Concrete is the most produced construction material in the world and has a close tie to carbon dioxide emissions. To reduce the gas pollution and resource drain of cement production and utilization, researchers have replaced some of the cement and natural aggregate content with industrial by-products such as steel slag, ferronickel slag, …
The slag from this process contains 8-11% of copper. In the new concentrator the slag will then be processed to maximize copper recovery and …
Smelting energy is generated by the exothermic reaction, which occurs because of the interaction of sulphides and coal with oxygen. The resulting melt separates into two layers in the hearth section of the furnace. The denser molten matte layer contains copper-iron sulphides below the unwanted upper slag layer which contains waste oxides.
from copper, the copper smelter slag can also be a significant source of iron and silica [15-18]. The reverberatory furnace slag that was discarded in the vicinity of the Bor Copper Smelter, Serbia, is currently processed by flotation at the nearby Bor Copper Concentrator. The copper recovery has been rather low mainly due to the presence of ...
