calcination gold sulfide ore in japan

Gold ores are considered refractory if gold extractions from a conventional cyanidation process are less than 80 even after fine grinding 1 Arsenicbearing refractory gold ore has stones extremely difficult to deal with In the stones gold is locked up in arsenic mineral matrix as the form of microscopic or submicroscopic lattice...As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
