sulfuric acid slag magnetite ore ball mill

The grinding was carried out at room temperature using tap water. 400 g magnetic concentrate sample at 66.7% solid density was ground in a ball mill to gain an 85 wt % passing size of 74 μm. The mill discharge was transferred to a 1.0 dm 3 XFD-type laboratory flotation cell

A process for preparing ferrous sulfate includes such steps as reaction between waste dregs containing 3-valence Fe and sulfuric acid at 80-130 deg.C to obtain acidic solution of iron sulfate, adding troilite or sulfur ore concentrate to obtain ferrous sulfate solution, cooling to -10-20 deg.c for crystallizing, filtering, centrifugal drying and baking to obtain FeSO4.7H2O

Apr 01, 2019 · For each leaching experiment, 10 g ore was leached in 0.5 dm 3 of 1 mol/dm 3 sulfuric acid solution. Leaching was performed at room temperature, under magnetic stirring for 24 h. To fit experimental data with shrinking core model, initial particle size ranges was set at 35–53 µm, 53–75 µm, and 75–106 µm by sieving

3. Adapting to a wide range of industries: you can meet the needs of many industries, such as iron ore, river sand, tailings, steel slag, steel ash, sulfuric acid slag, abrasives, refractories, board, rubber, food, etc. Some of the equipment is also multi-purpose

Dec 17, 2015 · Sulfuric acid is required to bring metal values (i.e. Co, Ni and Cu) into the solution since most of cobalt and nickel, and part of copper are present in the form of oxides in the slag. Sulfuric acid concentration affects both the dissolution kinetics of base metals as oxides and eventually the amount of iron converted into hematite

Some impurities form a slag (such as FeO.SiO 2), which floats on the surface of the liquid (like oil on water) and is easily removed. (Courtesy of Xstrata.) The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores

The sulfuric acid treatment process of the slag, however, still suffered from the disposal problem of the waste acid and as a result it was abandoned in the 1980s and replaced by a new technology based on upgrading the slag to 94.5% TiO2 by leaching away most of the impurities by HCl under pressure to render it suitable for chlorination

The Sage autoclave processes refractory ore that contains high levels of sulphide minerals. The Sage mill includes a SAG mill followed by ball milling. The cyclone overflow reports to a thickener. Thickener underflow reports to an acidification circuit where sulphuric acid is added as necessary to ensure adequate autoclave free acid solution

Sulfuric Acid Slag Copper Ore Froth Flotation Machines GM stone crusher machine is designed to achieve maximum productivity and high reduction ratio.

Uranium extraction from ore involves the use of acid or base to break own and extract uranium from the raw ore. These processes require significant amounts of acids or bases, the most commonly used being sulfuric acid and sodium carbonate, respectively

This slag is the world's principal raw material for vanadium production [3, 4]. Moskalyk and Alfantazi [4] reported that a roast–leach process is used in South Africa for the production of vanadium oxides from magnetite ores while some of the slag was converted to ferrovanadium
