Metal Extraction Processes for Electronic Waste and Existing Industrial Routes: A Review and Australian Perspective Abdul Khaliq, Muhammad Akbar Rhamdhani *, Geoffrey Brooks and Syed Masood Faculty of Science, Engineering and Technology, Swinburne University of Technology, Hawthorn,
They usually contain a quantity of valuable metals except for BF slag. Recovery of metals from the slags and uitilization of the slags not only can save metal resource, but also can protect the environment. (2) Ferrous slags mainly include iron slag, steel slag, alloy steel slag and ferroalloy slag.
The slag contains gold and silver and must be reprocessed in order to minimize the losses of precious metals. A very important element in the smelting process is the flux, which is added to charge in order to remove base metals and other impurities from the Dore bar.

Apr 06, 2013· Aluminum Dross Recycling Machine is mainly used to separate the aluminum metal form the Aluminum dross or aluminum ash, it can reusage the aluminum metal from the aluminum dross to avoid wasting.
oxide. The purity of Niobium metal extracted was calculated to up to 95% which means that tin slag from Nigerian Tin Smelting Company is a good source of high quality Niobium metal. Properties Index Terms Tin slag, Niobium, carbonchlorination, leaching, extraction, particles, reaction Heat Capacity Coefficient of Linear I. INTRODUCTION
The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as Iron silicate slag. Most of the sulfur in Chalcopyrite turns into Sulphur dioxide (SO 2).
Slag removal system is a selfcleaning cutting table by Koike Aronson. There is no need to stop production to remove your slag. Klean Sweep operates and removes slag and scrap while you cut on demand or on programmed intervals.

The calcium silicate melts and runs down through the furnace to form a layer on top of the molten iron. It can be tapped off from time to time as slag. Slag is used in road making and as "slag cement" a final ground slag which can be used in cement, often mixed with Portland cement.
I''d like to know which way will be ok to extract metals from steel slags Leaching or flotation or xYz? Which one is more suitable whereas some elements like Si and Al extract lower Here is the composition of steel slag: SiO2 18%Al2O3 4% CaO 32% MgO 9% FeO 32% MnO % P2O5 1% TiO2 1% V2
The metal ore is either distilled in a electrolyte or acid solution, then magnetically deposited onto a cathode plate (electrowinning); or smelted then melted using an electric arc or plasma arc furnace (electrothermic reactor). Another major difference in nonferrous extraction is the greater emphasis on minimizing metal losses in slag.

The Slag Raking Machine is used to rake the slag layer from the surface of molten metal. It can be used on iron and steel ladles, aluminum holding furnaces and in other hot metal areas. This reduces the metallurgical load. It is a hydraulically operated machine of sturdy construction for use in steel plants.
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. The anode sludge will contain valuable metals such as silver and gold. Metals above copper in the electrochemical series (like zinc) will form ions at .
