Finally, zinc is precipitated as carbonate and recovered from the solution. (Chen et al., 2017) used a combination of concentrated sulfuric acid and ascorbic acid as a reducing agent to recover zinc from battery waste. Table 9 summarises the rate of zinc recovery from battery waste achieved ...
The wet process for producing zinc oxide is based on the zinc-containing material, and firstly, a zinc-containing solution is prepared, and then a zinc compound (such as zinc carbonate) which is easily converted into zinc oxide is precipitated from the purified zinc-containing solution, and zin...
Usually, sulphuric acid, hydrochloric acid, ammonia/ammonium carbonate, ammonium chloride, caustic soda, carboxylic acid etc. are used as lixiviants for the dissolution of zinc. Different processes developed on bench, pilot and commercial scale have been highlighted. The metal from the leach solution...
The sulfur dioxide is used for the production of sulfuric acid, which is necessary for the leaching process. If deposits of zinc carbonate, zinc silicate or zinc spinel, like the Skorpion Deposit in Namibia are used for zinc production the roasting can be omitted.[82] ...
(MO) to give derivatives of the formula MZnOCl2. This reaction is relevant to the utility of Zinc chloride as a flux for soldering - it dissolves oxide coatings exposing the clean metal surface. Typically this flux was prepared by dissolving zinc foil in dilute hydrochloric acid until the ...
The CO2 is blown or the acid, such as hydrochloric acid, is added to this soln. to adjust the pH to 7 to 9.5 and the liquid temp. is regulated to 10 to 60 deg.C to settle ZnCO3. The precipitate is washed by methanol, etc., after filtration and is dried at room temp. to 200...
