Till now, majority of studies on processing and beneficiation of feldspar ore focused on removal of those phases which are considered as harmful colouring admixtures in ceramic/glass industries [44,45,46,47]. In order to make the beneficiation process effective and economic, any Fe-, Ti or Mn-bearing phase is considered as harmful.
Amarante et al. studied the beneficiation of a Portuguese feldspar ore by magnetic separation followed by froth flotation with HF or H 2 SO 4 as the pH regulators and commercial amine acetate collectors like Armoflote 820 and 543. They found that a final feldspar concentrates with K 2 O of 13.87% could be enriched from the feed K 2 O value …
The feldspar slime generated during beneficiation processes contains a high content of colored iron-bearing minerals, which is an obstacle to its utilization. In this study, dishwashing liquid is used as the flotation collector and frother, and combined beneficiation processes, including wet ball milling, froth flotation and magnetic and ...
Beneficiation is the process of removing unwanted minerals or impurities from ore to increase its value or quality. However, extracting and processing lithium from its ore is challenging due to its complex chemistry and the presence of impurities. Lithium ore beneficiation processes involve crushing, grinding, gravity separation, flotation and ...
