Separation of Lead from Crude Antimony by Pyro-Refining Process .

Abstract: The main purpose of this study was to separate lead from crude antimony through an oxidation pyro-refining process and by using sodium metaphosphate as a lead elimination reagent. The process parameters that will affect the refining results were optimized experimentally under controlled conditions, such as.

Lead Refining Plant, Lead Refining Technology, Recycled Lead .

A smelting plant stops at the stage of the fusion-reduction plant; it will produce what is known as hard or Antimonial Lead. If the plant is meant to produce soft Lead, the crude Lead must undergo a refining process. The objective of the refining process is to remove almost all copper (Cu), antimony (Sb), arsenic (As) and tin.

Antimony (Sb) - Chemical properties, Health and Environmental effects

Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis. Antimony and some of its alloys expand on.
