Antimony Poisoning in Industry. - CAB Direct

The average zone concentration of antimony in the electric furnace area in an initial survey was 10 mgm. per cu. metre of air, and in the breathing zone area 0.92-70.7 mgm. per cu. metre. The corresponding values for arsenic were 1.1 and 0.04-4.66 mgm. A further hazard in the process consisted of an alkaline mist which occurred in the refining ...

Antimony Recovery from End-of-Life Products and

2016-2-8 · Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and

PAPER OPEN ACCESS Melting of crude antimony in the

It is proposed to use an ore-thermal furnace with a capacity of 0.35 MW as the main unit for the antimony production. The electric furnace is devoid of a number of drawbacks inherent in reflective furnaces. Thus, the absence of a gas flare contributes to the release of less gases, which reduces the possibility of entrainment of antimony with them.
