extraction of ferrous sulphate from scrap iron experiment

Cleaner Extraction of Lead from Complex Lead-Containing

and other ferrous wastes. However, compared to the primary sulfide concentrate, the sulfur content in wastes is too low to provide enough heat for the smelting when considering the endothermic decomposition reactions of sulfate [22]. Therefore, the use of waste materials often leads to an unstable smelting operation.


You can make your own iron mordant (called iron liquor or ferrous acetate) by putting some scrap metals - like old nails - in a glass jar and cover it vinegar (or part vinegar, part water) This won't be as precise because the amount of iron sulphate increases overtime. Just start with adding a little bit to a pot of water and add more until you

Leaching of impurities for the up-gradation of molybdenum oxide and cementation of copper by scrap iron

2008/8/1 · The experiment for the cementation of copper from the obtained leach liquor containing 20 g/L copper was carried out using scrap iron sheet/splinter. The 100 ml of leach liquor was taken. The pH of the leach liquor was adjusted below 0.9 ( van den Berg et al., 2002 ) by adding 7 ml of conc. H 2 SO 4 in the solution.

Iron Removal and Recovery in the Titanium Dioxide Feedstock and Pigment Industries

Iron oxide based-electroactive IoNanofluid with high dielectric constant, high stability and low viscosity was synthesized from ferrous sulphate heptahydrate via a

How to Treat Wastewater from Iron and Steel Industry? | Waste

Most of the ferrous sulphate wastes are treated with lime to make them alkaline. The solutions are then transferred to lagoons where soluble ferrous hydroxide oxidises to ferric hydroxide, which precipitates, aided somewhat by water evaporation. In this way, iron is disposed of by land storage and clean effluents are produced.

Non-ferrous extractive metallurgy - Wikipedia

Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. Metals like zinc, copper, lead, aluminium as well as rare and noble metals are of particular interest in this field, while the more common metal, iron, is considered a major impurity.

Recovery of iron from waste ferrous sulphate by co-precipitation

2017/1/1 · Magnetite concentrate was recovered from ferrous sulphate by co-precipitation and magnetic separation. In co-precipitation process, the effects of reaction conditions on iron recovery were studied, and the optimal reaction parameters are proposed as follows: n(CaO)/n(Fe 2+) 1.4:1, reaction temperature 80 C, ferrous ion concentration 0.4 mol/L, and the final mole

Ferrous sulfate is useful in chemistry as a reducing agent and a source of ferrous ions. It can also act as a catalyst; an example is Fenton's Reagent, which is used to destroy organic chemical wastes. Ferrous sulfate's systematic name is iron (II) sulfate, with the "II" referring to the +2 valence state of iron.
