PROCESS FOR REMOVING IMPURITIES IN THE LIQUID OF

What we claim is 1. A process for removing impurities in a zinc sulphate solution obtained by leaching calcined zinc ores with sulphuric acid which comprises treating said solution with metallic zinc and removing precipitates thereby formed, thereafter adding to the solution hydrogen peroxide in an amount sufficient to oxidize ferrous iron contained in the solution to ferric iron, thereafter ...

Simultaneous Removal of Fluorine and Chlorine from Zinc ...

2017-12-27  During the zinc electrowinning process, fluorine (F) and chlorine (Cl) ions can cause corrosion of the anode plate and difficulty in stripping the zinc cathode sheet. Because of the increasing use of F/Cl in zinc concentrate in industrial production and the stricter requirements of large-size cathode technology (LARCATH), it is very important to remove F and Cl fully from the zinc sulfate ...

Iron contamination / buildup problem in acid zinc plating

2008-5-10  A little iron is ok, but too much iron can cause problems. Iron plates out in the high current density areas and chromates much darker than does zinc (iron causes the black spots in zinc barrel plating). The iron can be controlled by using hydrogen peroxide. Use about 500 mls per 370 liters (35% hydrogen peroxide mixed about 50/50 with water to ...

Iron recovery from sulphate leach liquors in zinc ...

2003-1-1  Abstract. Iron is usually present in leach solutions and its elimination is a major operational problem in zinc hydrometallurgy. The recovery of iron from such solutions is usually carried out by precipitation as jarosite, goethite or hematite. These residues, contaminated with heavy metals ions such as Zn, Pb, In, Ga, Ge, Co and sulphur, are ...

How to remove Sulfate from water

1. Reverse Osmosis (RO) is a water treatment system that removes most dissolved substances, such as sulfate, from water by forcing the water through a cellophane-like plastic sheet known as a "semipermeable membrane." It can typically remove between 93 and 99 percent of the sulfate in drinking water depending on the type of unit.
