NICKEL AND COBALT ORES: FLOTATION

2016-6-7  A typical example of a nickel sulRde plant operat-ing with highly Soatable talcose gangue is at Trojan mineinZimbabwe.TheZimbabweansulRdedeposits contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This

Enhanced methods for nickel recovery from low-grade

2021-10-16  Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4% Ni to 10-20%. Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel
