Separation of arsenic from lead smelter ash by acid

1. Introduction. Arsenic is used associated with metal ores and recognized as a harmful element in non-ferrous metal smelting process,, .In the smelting process of copper, lead and zinc, a large amount of arsenic-containing hazardous wastes such as smelter ash are produced,.Arsenic content in smelter ash ranged from 5% to 40% .As it is known to all, arsenic and inorganic arsenic

Selective Separation of Arsenic from High-Arsenic Dust in

2021-5-14  Abstract The selective separation of arsenic in the NaOH-S system from arsenic dust containing Pb, Sb, and Zn was studied by central composite design response surface method in this investigation. The results indicated that the presence of elemental sulfur can prevent lead and antimony leaching from arsenic

Separation of arsenic and extraction of zinc and copper

Separation of arsenic and extraction of zinc and copper from high-arsenic copper smelting dust (HACSD) is one of the difficulties in the world. A two-stage countercurrent alkali leaching followed by one-stage sulfuric acid leaching for arsenic separation and zinc and copper extraction was developed in this work.

Separation of arsenic and tin from Cu–As alloy based on

Separation of arsenic and tin from Cu–As alloy by vacuum distillation in the presence of pyrite to form new phase was investigated. Some conclusions were drawn as follows: (1) Arsenic was difficult to be separated from Cu–As alloy by direct vacuum distillation. Improving temperature make volatilization ratios of Cu and As simultaneously

Distillation and separation of arsenic, antimony, and tin

2012-6-22  Scherrer] Separation oj Arsenic, Antimony, and Tin 255 over the vapors from the distilling flask O. The part of this tube extending into B should have a diameter of not over 3 to 4 mm in order to prevent the acid from draining from it.

A comment on arsenic species separation using ion

2000-3-1  The Ficklin anion exchange method for separation of arsenate and arsenite is a solution to the problem of preservation of arsenic species. Ion exchange separations, in the field, of arsenite and arsenate are necessary because there are not suitable sample preservation methods that will maintain the arsenate/arsenite ratio, or suitable field separation techniques

Separation and recovery of arsenic and alkali products

2020-7-1  Efficient separation and recovery of arsenic and alkali were achieved. • Low consumption of sulfuric acid in the process of deep alkali removal. • The products recovered from arsenic-alkali solution were Na 2 CO 3 and As 2 O 3. • No arsenic-alkali mixed salts were produced in the separation process of arsenic and alkali.

Separation of Arsenic and Extraction of Zinc and Copper

2021-7-6  Separation of arsenic and extraction of zinc and copper from high-arsenic copper smelting dust (HACSD) is one of the difficulties in the world. A two-stage countercurrent alkali leaching followed by one-stage sulfuric acid leaching for arsenic separation

Thermal separation of arsenic and antimony oxides

Experiments were carried out to remove arsenic from antimony trioxide by two techniques: first, by selectively volatilizing the more volatile arsenic trioxide from a mixed oxide sample; and, second, by selectively condensing the less volatile antimony tetroxide at high temperatures, leaving arsenic trioxide to condense out at a lower temperature. Thermodynamic analysis of the As-Sb
