We provide leading process technologies and services for metals and mining, industrial water treatment, alternative energy, and chemical industries.
recoveries of Cu and Sn from refining slags, size reduction, flotation, and leaching tests were performed and results are given in the following sections: Size reduction experiments The maximum particle size of the slag was around 150mm, as received. They were first crushed below 19mm by using primary and secondary crushers.

slag flotation of copper ... plant produces about 40,000metrictonnes of blister copper and about 150,000 metric tonnes of flotation waste per year. For nearly 5,000 years, copper was the only metal known to .
Copper Flotation Elmhurst College. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and groundup limestone) to give a basic pH, pine oil (yes, it comes from trees a byproduct of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a ...

copper recovery magnetic slag excellent mining crushing machinery products or production line design, the company is committed to building the Chinese brand mine crushing and processing machinery, mainly crusher, mill, sand making our products (copper recovery magnetic slag) in more than one hundred of the worldsales of countries and regions.
According to the coexistence theory of slag structure, a calculation model for the activity of FeO in the quaternary system SiO2CaOAl2O3FeO of depleted copper slag was established. The model was used to calculate and analyze the effects of temperature (T), basicity (B), and Al2O3 content on the activity of FeO (NFeO). The results show that temperature has little impact on NFeO.
At San Manuel, the slag reprocessing operation was designed to extract copper values From slag using an existing flotation operation. Prior to flotation, slag is cooled, crushed. and milled. The flotation operation uses one of the eight existing ore flotation circuits in the mill to produce a copper concentrate which is then resmeited. Slag from the converter at San Manuel contains from 5 to 7 percent copper. .
For example, Falconbridge Kidd recycles dust from the waste heat boilers and cyclones at the copper smelter back to the concentrate dryer to be recycled to the smelting furnace. The dust from the electrostatic precipitator in the Copper Smelter is processed in the Zinc Plant to produce a copper residue, a lead/silver residue and a zinc solution.
LATEST RESULTS OF THE SLAG CLEANING REACTOR FOR COPPER RECOVERY 197 Metallurgical principles of conventional slag ... promising results of very fast slag reduction and effective metal recovery. Additionally, pilot tests (1–2 tph of slag charge) had been ... • Copper slag • Lead and zinc slag • Waste material • Ferro alloy slag13.
reduces the content of magnetite and slag viscosity. Copper particles are released to form a rich copper matte (>70% Cu) Slag cleaning in an electrical furnace: Copper is recovered by direct electrical reduction of magnetite, releasing the suspended inclusions while oxides are reduced by the graphite electrodes.
SECONDARY MATERIALS. KPM works on a number of projects related to recycling metals and treating secondary materials. Projects include the treatment of base metal production slag for further metal recovery, recycling and treatment of byproducts from base metal production, recycling of light metals, and removal/neutralization of toxic elements from hazardous waste.
Rio Tinto Kennecott Smelter; Rio Tinto Kennecott Smelter 20 Years Strong. The Rio Tinto Kennecott (RTK) Smelter near in Salt Lake City, Utah is entering its 20 th year of operation since the Smelter Modernization Project in the early 1990's when flash smelting and KennecottOutotec Flash Converting was first implemented.
The selective reduction impoverishment of slag from copper smelting with addition of charcoal powder and stirring of inert gas is investigated by the aid of metallurgical analysis, SEM and EDX. The results show that the copper content in the slag can be reduced from 5 % to % by the selective reduction impoverishment process.
material into a highcopper blister and a lowcopper slag. The slag is directed to the electric slagreduction furnace via a manual tapping process, which uses a coke reductant to capture most of the remaining copper. The molten blister copper is tapped from both the flash and electric furnaces (see
control mixture. However, addition of more copper slag resulted in strength reduction due to the increase in the free water content in the mix. Also, the results demonstrated that surface water absorption decreased as copper slag content increases up to 50 % replacement[5]. Therefore it
Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquidtosolid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.
Utilization of Waste Copper Slag to Produce Directly Reduced Iron ... to the high content of Cu, Pb, Zn and S in copper slag, but also wastes ... magnetic beneficiation, producing iron .
