20/10/2015& 0183;& 32;In the present paper an attempt has been made to beneficiate iron ore tailings by selective flocculation using guar gum and starch as flocculants along with sodium hexametaphosphate SHMP as the dispersant. The mineralogical studies carried out initially indi ed the presence of hematite and goethite as major iron bearing mineral phases along with quartz and kaolinite as major
important lithium ore mineral. A typical run of mine ore can contain 1-2% Li 2 O while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O 75% - 87% spodumene . Higher grade concentrates with 7.6% Li 2 O and low iron content are used in ceramics and more demanding industries.
& 0183;& 32;Nov 01 2020& 0183;& 32;1. Introduction. Mine tailings are side streams from ore separation which accumulate at the mining sites without economic utilization. The waste from mining and quarrying occupies more than half of total industrial waste according to a 2006 Eurostat report Castro-Gomes et al. 2012 .Management of these wastes pose a potential risk to the landscape in the form of

The froth mica concentrate and tailings purified kaolin were recovered and analyzed. Results are summarized in table form. Metallurgical results in the table show that froth flotation of the pulp of the impure clay with a phosphate ester complex as the collector reduced the mica content of the clay from 22.6 percent to 12.3 percent at a clay recovery of about 62 percent.
99% respectively. After the heat treatment nanocrystalline zincite clusters of 96.6% purity were produced in the ZnO mineral form and nearly 13 nm in size. Zinc can be successfully recovered and a flotation tailings ore can be a good candidate for the production of high technology needs of nanocrystalline ZnO nanoparticles.
