Sentence examples for leaching operation from inspiring English sources

Jarosite is a solid waste produced from hydrometallurgy operations involved in extraction of Zinc, in which, initially the Zinc ore concentrate (contains ~ 50% zinc) is roasted at 900 °C and then exposed to leaching operation where iron residual (jarosite) is produced as a waste [37]; Mymrin and Vaamonde [21, 32].
