• Flotation process • Sodium Ethyl Xanthate • Carbon Disulfate OVERVIEW The mining industry uses chemicals as 'flotation' agents in the recovery of sulphide minerals containing metallic elements (e.g., copper, nickel, silver, gold) from ore slurries. Sodium Ethyl Xanthate (SEX) is one of most common flotation agents, and it decomposes to Ethanol and Carbon Disulfide / Carbonyl Sulfide, which must be monitored in indoor air in the enriching plant. Xanthate solution is stored in tanks, which need periodic cleaning due to sludge buildup as the chemical decomposes over time. Removing the sludge releases sulfur containing gases (CS2, COS) and the cleaning interval varies from 3 to 12 months. In the actual flotation process, workers involved in checking flows, the head tank or in adjusting and monitoring the pulp levels in the flotation process could be exposed to CS2. A portable FTIR multi-gas analyser provides accurate and reliable readings for CS2 and COS with simple calibration (zero calibration only) and straightforward operation. The standard configuration contains up to 25 gases, making the instrument a versatile tool for occupational health measurements involving various mining chemicals. Left and above Short term and periodical measurements can be carried out with the battery powered portable analyzer and wireless handheld computer in field conditions.
