Beneficiation of massive ilmenite by froth flotation

May 01, 1986· INTRODUCTION The various processes used for ilmenite beneficiation are chemical, pyrometallurgical and by mineral dressing. The chemical methods which include selective reduction (Volk and Stottler, 1970; Sankaran et al., 1972), selective chlorination (Patel and Jere, 1960; Sankaran et al., 1968), selective leaching (Tikannen et al., 1963

Microwave Acid Leaching of Beneficiated Ilmenite for the

Microwave leaching experiments were carried out at temperatures 60, 70, 80, 90 and 100 o C for studying the effect of temperature on the dissolution of iron from beneficiated ilmenite.All the leaching experiments were carried out for 30 minutes with 7M HCI, at solid — liquid ratio of 1: 6 ( w/v).

US3660029A Process for beneficiating ilmenite Google

A process for treating ilmenite to obtain a beneficiated product having a relatively high titanium dioxide content. Particulate ilmenite is first heated in the presence of a reducing agent to reduce the iron compounds in the ilmenite to ferrous oxide and/or metallic iron. The resulting product is then leached with a dilute inorganic acid to solubilize the reduced iron values.

Recent developments in processing ilmenite for titanium

Dec 01, 1974· From the foregoing it shows clearly that selective chlorination is capable of upgrading ilmenite to an acceptable further use in converting TiO2 into TIC14. 299 A recent Dupont patent (Cairns, 1969) deals with the preparation of titanium tetrachloride from ilmenite by the total chlorination at 850--1,050: 2FeO.TiO2 + 6C + 7C12 ~ 2TIC14 + 2FeC13

Leaching of ilmenite in HCl H2O, HCl CH3OH H2O and HCl

Jan 01, 1990· INTRODUCTION Hydrochloric acid is used as a leachant in many processes [1,2,3,4] for up- grading ilmenite into synthetic rutile. The need for high acid concentrations and temperatures render the selective leaching of iron from untreated ilmenite using hydrochloric acid economically unattractive. Pre-treatment of ilmenite enhances its reactivity.

US5595347A Process for separating ilmenite Google Patents

A process for enhancing ilmenite from deposits of mineral sands or mineral concentrates comprises a single stage fluidized bed magnetizing roast (16). A temperature of 650° C.-900° C. in an excess of a carbonaceous fuel (such as coal/char, CO or hydrocarbon) is used to provide an atmosphere in which the oxygen potential is controlled resulting in a consistently high
