Mineral Beneficiation

The paper describes a machine developed for the purpose of concentrating clear optical grade fluorspar crystal from a feed material containing less than 1 pct impurities. The principle of concentration is based on the fact that in a liquid having an index of refraction equal to that of fluorite (n — 1.434) clear crystals are invisible, whereas crystals …

Fluoride in workplace air and in urine of workers concentrating fluorspar

Abstract. The urinary fluoride concentrations of workers exposed to calcium fluoride (CaF2) during fluorspar processing were measured. Personal dust measurement showed that the mean occupational exposure to fluoride for 12 workers in the most dusty environment was 24.3 mg/m3, which is 9.7 times the threshold limit value (TLV) of 2.5 mg/m3.

Concentrated solar power plants: Review and design methodology

A higher concentrating ratio of the sun enables the possibility to reach higher working temperatures and better thermodynamic efficiencies. On SPT plants, the large amount of irradiation focused on a single receiver (200–1000 kW/m²) minimizes heat losses, simplifies heat transport and reduces costs [13].
