Abstract
A four-step, bench-scale process has been developed that is capable of removing at least 92 percent of the soluble fluoride from feldspar flotation process wastewaters at a projected cost of $1.03/kkg ($0.93/ton) of feldspar. For a 163,000 kkg/year (180,000 ton/year) plant, the initial capital expenditure would be about $200,000. The wastewater is pretreated with sodium hydroxide, lime, and calcium chloride, which removes an initial 50 to 60 percent of fluoride. The clarified water is then passed through a bed of activated alumina for further fluoride removal. The activated alumina is regenerated with a 1-percent sodium hydroxide solution, and fluoride in the caustic liquor is effectively precipitated with calcium chloride. The fluoride can be recovered in concentrated form as insoluble calcium fluoride filter cake.
