A Review of Flotation Separation of Mg Carbonates

It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. The objective of the present study is therefore to investigate the effect of water structure on the flotation of selected carbonate and bicarbonate salt minerals: Na 2 CO 3, K 2 CO 3, NaHCO 3, and NH 4 HCO 3. Systematic experiments have been conducted to better understand the flotation response of these salts in terms of water structure.Water structure and its influence on the flotation of carbonate

Minerals Free Full-Text Influence of Mineralogy on the Dry

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 High-phosphorus manganese ores provide an important source of manganese, which is regarded as an irreplaceable material in the steel industry. The ammonia-ammonium carbonate leaching method was proposed for the removal of phosphorus and extracting manganese from high-phosphorus manganese ore, both Removal of Phosphorus from High-Phosphorus Manganese
