  Role of silica and alumina content in the flotation of iron ores

  2016310 · The flotation results with oleic acid and dodecylamine show better recovery of iron values in the hematite–quartz mixture as well as in the naturally occurring high silica ore compared to the hematite–clay mixture and the high alumina ore respectively. Similarly results on a variety of iron ores show that high silica content as quartz in ...

  Challenges in processing nickel laterite ores by flotation

  2016610 · In particular, it focuses on the mineralogy of laterite ores, liberation of nickel bearing particles, and challenges in separation of these particles by flotation. Other factors which influence the flotation process including selective aggregation of fine particles, and particle–particle interactions are also discussed.

  Bauxite Beneficiation: An Approach to Value Addition in …

  202172 · The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values. This often requires more complicated processes, such as the use of a high-intensity wet magnetic separator, with fine grinding of bauxite to liberate the iron minerals.

  Existing and New Processes for Beneficiation of Indian Iron …

  202028 · 2 Problems Associated with Indian Iron Ores Most of the integrated steel plants prefer to use high and medium grade ores in the form of lumps and fines. The sponge iron plants require only high-grade ores with certain specific size (− 18 + 5 mm). However, due to the supply of lower grade iron ores, and higher levels of impurities like silica and …
