Oct 01 2012nbsp018332Highlights Fusion of a Brazilian wolframite concentrate low P As and Si content with NaOH Tungsten was leached 986 wt with water after fusion at 650 176C for 1 h Tungsten extraction and stripping were easily run with Alamine 336 as the extractant Tungsten recovery in high yield as APT with very low phosphorous content
The best extraction with atmospheric leaching was 40 pct and obtained on ore calcined at 900176 c the effect of duration of calcination on tungsten extraction is shown in figure 3 a calcination time of 2 hr yielded tungsten extractions 2 or 3 pct higher than a 1189
