surface of the molten metal and agglomerate as a slag. Once the nonmetallics coalesce into a floating mass on the liquid metal they can be removed. The use of fluxes accelerates these processes. In some instances, oxides may have a lower melting point than the prevailing metal temperature and a liquid slag .

TBRC is a rotary tiltable furnace for smelting anode slime,WEEE,non-ferrous metal smelting slag and setting slurry to recover gold, silver and other precious metal. It can also treat copper concentrate and secondary material like scrap copper, scrape lead, lead slag, lead dust,etc.

Custom-designed for each application, our slag processing plants keeps the maximum environmental impact in mind. At our Metal Recovery Plant, a crushing and magnetic separation process is used to recover the metal contained in iron and steelmaking slag. This can then be effectively reused in the steelmaking process.

Recco. As a specialist in the recovery of non-ferrous metals from slags, or bottom ash (IBA), Recco facilitates a state-of-the-art system that separates the aluminium and heavy metals in 3 grading sizes from residue aggregates. The yield of aluminium and heavy metals we generate with our on-site bottom ash processing installations is, on average, 1,5 % higher than conventional recovery systems ...

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 .

If we accept the evidence presented elsewhere (7) that metallic Fe is the effective (intermediary) reductant in the process, it may be more correct to say that the recovery of valuable metals is related to a combined function of the iron and non-ferrous metal contents of the initial slag. Figure 4 - Recovery of Co to the alloy, as a function of ...

Development of Heat Recovery System from Steelmaking Slag condition. In case that the molten slag have enough flu-idity, molten slag spread across the full width of the rolls and was continuously solidified with the rolls. Figure 4 shows an example of the slag surface tem-perature measurement results with an infrared thermog-raphy.

Sep 21, 2012· In the quest to achieve the highest metal recovery during the smelting of copper concentrates, this study has evaluated the minimum level of soluble copper in iron-silicate slags. The experimental work was performed under slag-cleaning conditions for different levels of Fe in the matte and for a range of Fe/SiO2 ratios in the slag. All experiments were carried out under .

Metal Recovery Systems LLC is an environment conscious recycling and repurposing business, minimizing metal debris into the waste stream. Over the past 8 years we have helped our clients reclaim metals and reduce excess waste. ALL while helping our clients save money. We make this process simple, as it should be.

Dross & Slag Metal Reclamation Systems DIDION Rotary Dross / Slag Metal Reclaimers liberate and reclaim valuable metallics from large slag & dross chunks using a patented design. The machine features a Dynamically Isolated Articulated Concentric Crusher with serrated teeth that provides a positive action for reducing large chunks.

Sensor-based sorting is also completely dry, requiring no water or expensive water treatment system, and allowing long operational uptimes under constant conditions. Benefits of sensor-based slag metal sorting at a glance: Free metal recovery: Separating non-magnetic metallic particles effectively means earning revenue at low cost.
