rheological method for hydrometallurgical recovery of base metals from ores and method for improving rheological characteristics of a laterite or other oxide ore

摘要

rheological method for hydrometallurgical recovery of ore base metals and method for improving the rheological characteristics of a laterite or other oxide ore such as ore nickel, comprising the steps of combining a sulfide or concentrate (10) ore with a laterite or with another oxide ore (12) and grinding them together in a grinding circuit (14) to form a combined sludge with improved rheological characteristics. the combined and milled ore from the grinding circuit 10 (14) is subjected to a sieving step in the sieving circuit (18). the smaller size ore is routed from the screening circuit (18) to a sludge tank (19), and the combined slurry is then pumped to an acidic bleach circuit under pressure.
