Carbothermal reduction of copper smelter slag for
1/6/2017· Clearly, the results can help sustain the metallurgical industry, allowing for copper smelter slag to be recycled into valuable products, namely pig iron (after arsenic removal) and secondary slag (glass), and simultaneously leading to the restoration of contaminated sites to their near-natural state before. Similar exercise was undertaken with another initial slag from an operating smelter
Recovery of metal values from copper slag and reuse of
Copper slag was characterized and processed. The pyro-metallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440°C) helped recover a majority of the metal values (e.g., Fe, Cu and Mo) into the iron-rich alloy product which can be a feed material for steel making. On the
Recycling of Copper
Where copper and copper alloy scraps are very contaminated and unsuitable for simple remelting, they can be recycled by other means to recover the copper either as the metal or to give some of the many copper compounds essential for use in industry and agriculture. This is the usual practice for recovery of useable copper in slag, dross or mill scale arising from production processes or from
Effect of copper slag, iron slag and recycled concrete
1/9/2017· Copper slag can be obtained from the course of manufacturing of copper, F.G. Asl, M.

Cleaner recycling of iron from waste copper slag by using
Copper slag contains iron in the range of 42?45%, which can be recovered and recycled along with the contained copper to obtain an iron?copper alloy and a final slag rich in oxides. Therefore, the

On the
Reduction of Chilean copper slags: a case of waste
11/4/2005· Copper slag contains many useful metals and slag making oxides, which can be recovered and recycled by a high temperature direct reduction process. The laboratory scale tests show that by suggested high temperature direct reduction of copper slags two products can be obtained, a Fe–Cu–C alloy with precious metals content and an inert slag with low metal content. The Fe–Cu–C alloy can
Use of waste copper slag, a sustainable material
The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date. One of the greatest potential applications for reusing copper slag is in cement and concrete production. Many researchers have investigated the use of copper slag in the
Use of waste copper slag, a sustainable material
Copper slag is a by-product obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing

Copper slag Wikipedia
Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Such use was common in areas where smelting was done, including St Helens and Cornwall in England. In Sweden (Skellefteå region) fumed and settled granulated copper slag from the Boliden copper smelter is used as road-construction material. The
Copper Slag-Grit
Copper Slag-Grit is an abrasive sandblasting material made of granulated slag obtained during the It can be recycled Silicon crystal level lower than 1%. Grit is designated to multiple uses, it is of high density and it is made of slag that is obtained as by-product in copper production. Typically, grit contains iron oxide and silicon dioxide. Considering that copper grit contains a high
How Is Mining Waste Recycled? Ecocycle Australia
Slag Recycling. Slags are are the non-metallic components left over from metal smelting. They are largely environmentally safe and are increasingly being used in making concrete and in road construction. Metal smelting can also produce large amounts of sulphur dioxide, the cause of acid rain. Sulphur dioxide can be captured and converted to sulphuric acid, a major industrial chemical. There
Copper recycling and sustainability Benefits of recycling
Copper recycling and reuse. Reduce: Copper products are hard wearing and last for a long time and will often still function long after they have been superseded by newer models. Reuse: Goods such as mobile phones, washing machines and cookers, which are still in working order, can be passed on to others for reuse. Recycling: Copper containing waste such as WEEE (Waste Electrical and
