However we have several gold mines and exploration companies in Finland and Sweden as our customers and their recoveries have been 95100 gold in the cyanide leaching The recovery is measured by first leaching the sample with the PAL1000 cyanide leach and then the leaching residue is analyzed by fire assay for noncyanide leachable gold... 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.
