Carcinogenic effects of antimony trioxide and antimony ore concentrate in rats

Journal of Toxicology and Environmental Health, 1986
This study was initiated because of a suspected increase in incidence of lung cancer in antimony smelter workers in England. Three groups of 8-mo-old Wistar-derived rats (90 males and 90 females per group) were exposed by inhalation to either Sb2O3 [time-weighted average (TWA) 45 mg/m3], Sb ore concentrate (TWA 36 + 40 mg/m3), or filtered air (controls)

Preparation of antimony ore samples for determining the content of macro- and microcomponents by x-ray fluorescence analysis

, 2020
X-ray fluorescence is a convenient method for the quantitative analysis of antimony sulfide ores. A technique for preparing samples of antimony ores for analysis by high-temperature oxidation of samples in air has been developed and described.

Processing of Gold Bearing Antimony Ore

Mineral Processing and Extractive Metallurgy Review, 1995
A wet chemical process was developed for the separation of gold from gold-bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33% Sb in the form of antimonite. 24% Si in the form of quartz, small quantities of Pb, Fe, Cu, and Ni as well as 63 g/t gold, 60% of it as visible gold. The

Antimony Ore Identification Method for Small Sample X-Ray Images with Random Distribution

Minerals
The performance of image processing is crucial for accurately sorting antimony ore, yet several challenges persist. Existing image segmentation methods struggle with X-ray ore images that contain high noise and interference.
