antimony refining process 2011:

Recovery of alkali, selenium and arsenic from antimony

A new process was proposed to dispose antimony smelting arsenic-alkali residue. • The efficient recovery of alkali, selenium and arsenic was achieved. • Se was recovered in the form of elemental selenium without adding reducing agent. • The recycling process is clean and environmentally friendly.

Antimony process American, Smelting Refining

The process for preparing antimony oxide which comprises softening antimonial lead thereby yielding an antimonial slag, reducing and concentrating said slag into an antimonial product containing from 65% to 80% of antimony, volatilizing antimony oxide from said product, recycling the residual metal until the copper content builds up to approximately 8%, then withdrawing the residual metal, cooling same

01/07/2014· During the refining process in a reverberatory furnace, any As accompanying the antimony oxide is removed by the addition of sodium hydroxide. AAR is generated during the As removal process. DS is produced during the desulfurization of the smelting off-gas using limewater. The quenching water and cooling water are both reused. Thus, the primary heavy metal sources

Antimony Wikipedia

Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was

US4425160A Refining process for removing antimony

An improved process for refining lead bullion containing antimony, in which the bullion is initially heated in a refining vessel to about 25° F. (14° C.) above the bullion melting point, and is thereafter kept molten primarily by exothermic process reactions. The process includes the steps of melting the lead-antimony bullion, agitating the bullion, adding caustic soda and metallic sodium to

Lead and tin removal from antimony metal by refining

antimony refining at 800℃, which resulted in the lead decrease down to 0.015% versus its initial content of 4% in the rough metal. The method requires maintaining the ratio of P 2 O 5: Na 2 CO 3 = 3:1 and the rate of the refining mixture should be 20% of the metal weight. Furthermore, the lead-removal reagent [5] is proposed as the mixture containing 30-70% of the reagent with phosphorus

If softening (antimony removal) is desired, the same procedures employed during the Razor Process 14 for de-tinning can be employed again to remove antimony in the form of sodium and antimonate. Slightly higher temperatures will facilitate this reaction. Additionally or alternatively, conventional softening could be employed, depending on the nature of the refining by-product most advantageous
