Iron Precipitation (Goethite)- - Metalcess

The mainstay of iron precipitation includes jarosite, goethite and hematite, of which goethite is of the most economic and environmental-friendly superiority. Goethite residue from zinc hydrometallurgy can be treated by flash magnetization roasting.It can enrich the goethite residue into standard iron ore for sale. It is the best accessible green solution to recycle iron at high efficiency but low cost.

26-02-2021· Isothermal reduction experiments at 1400 °C, which used carbon-bearing pellets mainly made from Bayan Obo complex iron ore and pulverized coal, could effectively separate rare earth (RE) slag and iron. Different instruments were used to study the precipitation of RE slag and the growth behavior of the RE phase in RE slag during the process of cooling from 1400 °C.

Iron Control in Zinc Pressure Leach Processes

Careful control of the iron precipitation step is important, so that the iron residue produced is amenable to efficient liquid-solid separation in order to obtain high zinc recoveries. In hydrometallurgical zinc processes, the coprecipitation of minor impurities along with iron precipitation is also important in producing zinc-sulfate solution from which high-purity zinc cathode can be electrowon.

Jarosite/Goethite Precipitation for Iron Removal-Zinc-

3. Hematite precipitation has high iron content and can be used as raw material for iron smelting. But it proposes high demand in process and operation condition and the production cost is very high as there is repeated scaling problem with the autoclave. Metalcess usually recommends goethite precipitation for iron removal in zinc hydrometallurgy.

Precipitation of Ru, Rh and Ir with iron ions from ...

01-01-2018· At initial pH 2.5, the tests performed without seeding achieved more iron precipitation (79.1%) than the tests performed with seeding (68.7–75.3%); the apparent interference of goethite seed with iron precipitation could possibly be ascribed to the effect of goethite seed on mixing efficiency and reagent transport in solution.
