Performance Characteristics of Copper and Coal Slag Abrasives

Copper slags can be either water- or air-quenched (Fig. 1 and Fig. 2). Bottom or coal slags are most often water-quenched. Therefore, the purity of the quenching water and the cleanliness of the quenching basins have a significant effect on the cleanliness of the abrasive product. Secondary copper smelters are also a source of copper slag. These smelters

Copper slag is a by-product of copper separation during the smelting process. It is an aggressive abrasive used mostly in new steel manufacturing or in maintenance blasting. Its high bulk density and shape lend to fast cutting and increased production time.

Copper slag sandblasting abrasives (Iron Silicate)

Copper slag (Iron Silicate) abrasive has a HIGHER DENSITY THAN COAL SLAG (~20% HIGHER) AND WILL THUS BLAST FASTER THAN COAL SLAG, AND YOU CAN RECLAIM IT A COUPLE OF TIMES AS WELL. Copper will therefore result in less product consumption, less disposal cost, and overall, a more cost-effective media to use when compared with garnet,aluminum oxides,or

What is a Copper Slag? (with pictures) Info Bloom

Jan 28, 2021 Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.

Recovery of Iron from Copper Slag Using Coal-Based Direct

The Fe3O4 and Fe2SiO4 in copper slag were successfully reduced to metallic iron by coal-based direct reduction. Under the best reduction conditions of 1300 °C reduction temperature, 30 min reduction time, 35 wt.% coal dosage, and 20 wt.% CaO dosage (0.75 binary basicity), the Fe grade of obtained iron concentration achieved 91.55%, and the Fe recovery was 98.13%.

Isothermal Coal-Based Reduction Kinetics of Fayalite in

The effects of copper slag and phosphorus slag on the phase compn., heat release and compressive strength were investigated. The phase compn. was analyzed by X-ray powder diffraction. The results show that the copper slag and phosphorus slag can lower the burn temp. of the clinker and promote the coexistence of C3S and C4A3S[n.773].

Slag Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of

Copper slag as a catalyst for mercury oxidation in coal

Apr 01, 2018 Copper slag is a byproduct of the pyrometallurgical smelting of copper concentrate. It was used in this study to catalyze elemental mercury (Hg 0) oxidation in simulated coal combustion flue gas.The copper slag exhibited excellent catalytic performance in Hg 0 oxidation at temperatures between 200 °C and 300 °C. At the most optimal temperature of 250 °C, a Hg 0 oxidation efficiency of

In some tests, solid slag and coal were fed together, while in others the slag was first melted then the coal added afterwards. Coal (at 53% fixed carbon) additions varied between 4, 6, 8, 10, and 12 per cent of the mass of the slag. The mode of addition of the coal, and the reduction periods of the tests were also varied (around 30 minutes).
