A Process Mineralogical Evaluation of Chromite at the Nkomati
A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite. Chromite is a by-product of the Ni-Cu-Co-PGE ore at Nkomati Nickel mine. These being the PCMZ_MG (medium-grade Ni-Cu sulphide silicate Mineral Technologies has a long and successful history in the Southern African Bushveld region which contains approx. 75% of the world’s chromite reserves. Many of the most recent plant designs typically include the MG6.22 spiral in a multi-stage circuit. These plants are low in capital cost and deliver a high recovery of chromite concentrates.Fine chrome recovery Commodities Mineral Technologies

Characterisation and separation studies of Indian chromite
The total chromite deposits of the world and beneficiation prospects have been described by various authors (Atalay and Ozbayolu, 1992, Guney et al., 2001, Murthy et al., 2011). India is the world's third largest producer of chromite ore and produces about 3.5–4 MTPA. The estimated reserve of chromite deposit in India is about 187 MT.Issues in the industry. Data from Minerals Council South Africa shows that chrome ore production dropped to 14.5-million tonnes in 2020, from 17.7-million tonnes in 2019. The council’s head of communications, Allan Seccombe, said the decline is attributed to the Covid-19 pandemic.
