Extraction of Nickel from Garnierite Laterite Ore Using Roasting

In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing 0.72% Ni, 0.029% Co, 8.65% Fe, 29.66% MgO, and 37.86% SiO2 was collected in the Mojiang area of China. Garnierite was the Ni-bearing mineral; the other main minerals were potash The magnetic separation and extraction experiments of quartz concentrate from high‑silicon IOTs were conducted using an S-HSMS equipment designed by the Chinese Academy of Sciences [33], as shown in Fig. 1.The equipment was mainly composed of two superconducting magnets and a high gradient separator.Recovery and preparation of high-grade silica from iron ore

Influence of Mineralogy on the Dry Magnetic Separation of

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were Abstract: Pulsating high gradient magnetic separation (PHGMS) for removing trace amounts of iron impurities from a quartz ore was investigated using a lab-scale PHGMS separator, and its performance was further confirmed through a pilot-scale PHGMS separator.
