The Cu matte that is a byproduct of the Pbbased process, can be reused in the Cubased process. On the other hand, slag resulting from the Cubased process containing PbO is used in the Pbbased process. By combining the smelting processes for these two nonferrous metals, various metals can be recovered efficiently and simultaneously.
Steel slag is a waste material produced during the process of steel making. For many years, a large amount of steel slag was deposited in slag storing yards, occupied farmland, silted rivers and ...
BF slag is utilized in producing cement with large portion, the remaining is consumed for civil engineering such as for road construction [1, 2]. However, for the BF that has to use an ore with complex chemical composition or in low grade, the slag would be complex in chemical composition, especially if strong oxide forming elements are contained.

Aug 31, 2011· The bluegreen color is attributed to a complex reaction of sulfide sulphur in slag cement with other compounds in portland cement. In most concrete made with slag cement, the surface becomes light gray or white within hours after the concrete surface has been exposed to direct sunlight and air.
Tin processing Tin processing Mining and concentrating: Vein deposits, such as those in Bolivia and the United Kingdom, usually occur in granite formations and are recovered by conventional underground hardrock mining techniques. In deep mines, primary crushing equipment is usually located underground in order to reduce the ore to a manageable size before transportation to the surface ...
Slag, Metallurgical a melt (after solidifying, a rocklike or glasslike substance) usually covering the surface of molten metal in metallurgical processes, as the smelting of raw material, the processing of molten intermediates, and the refining of metals. Slags are alloys of oxides of various compositions. The major components of slags are the acidic ...
Steel Slag Material Description ORIGIN Steel slag, a byproduct of steel making, is produced during the separation of the molten steel from impurities in steelmaking furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.
The slag after crushing and grinding is fed to autoclave leaching. The optimal conditions of the leaching process, contributing to the full opening of the slag and extraction of germanium and zinc in the solution are: the lye concentration 20 wt.%, process temperature 200÷220°With the ratio of the phases W:t=5, time 6090 minutes.

In this case, ash and slag wastes processing can be disposable. Pilot plant tests confirmed lab tests results in terms of the quality of the resulting ironbearing concentrate and aluminum silicate product. The mass yield of ironbearing concentrate and aluminum silicate product in terms of ash and slag volume was 39 % and 4060 %, respectively.
Slag is the collection of compounds that are removed. In many smelting processes, oxides are introduced to control the slag chemistry, assisting in the removal of impurities and protecting the furnace refractory lining from excessive wear. In this case, the slag is termed synthetic.

Jan 01, 2020· The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: Blastfurnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast .
Coal is used in the production of other, perhaps unexpected products such as pharmaceuticals, textile dyes, food and wood preservatives, and other simple or highly complex chemicals (see centerfold). These chemicals typically are produced during the production of coke by a process .
The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a version of the basic oxygen process or in specialty steel plants (minimills) using an electric arc furnace process.
During all the processes that have been described so far slag, residues and flue dust have been produced. Normally these are worked into a previous stage of the process, but in primary work several products result which although poor in values compared with the .
