Hematite Processing by Flotation 911 Metallurgist

19-04-2016· Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with “Sub-A” Flotation to produce concentrates

FLOTATION CHEMISTRY OF HEMATITE/OLEATE SYSTEM

Currently beneficiation of hematite ores is conducted using either direct flotation (hematite flotation) or indirect flotation (quartz flotation) tech-niques depending upon the nature of the available ore bodies. In direct flota-tion, iron bearing mineral, mostly hematite, is floated using oleate as collec-

Journal of Physics: Conference Series PAPER OPEN ACCESS

iron ore (less than 40%) and it can produce high grade concentrates. Specialists of SP ZAO IVS has developed and patented a hematite ore flotation technology [1]. Hematite ores are different by mineral composition of host rocks and texture-structural features, which thus requires a thorough selection of flotation reagents.

Removal of hematite from silica sand ore by reverse

15-01-2008· Reverse flotation of hematite from a local silica sand ore has been investigated using a batch, bench-scale mechanical flotation cell. The effects of various operating parameters such as type and concentration of collectors, type of acid, pH, conditioning time, solid-in-pulp concentration, particle size and temperature have been studied on the hematite removal efficiency by reverse flotation.
