Sep 02 2020 · The Acoje block of the Eocene Zambales ophiolite NW Philippines is a fragment of forearc lithosphere in the Western Pacific and hosts a worldclass chromite deposit The compositions of chromitites dunites and harzburgites in the block are used to explore origin of ophiolitic chromite deposits during subduction initiation

It was also reported that beneficiation of fine size celestite tailings by MGS is possible Aslan et al 1996 In this study the applicability of an enhanced gravity concentration technique and magnetic separation for beneficiation of fine chromite from the magnetic tailings of the GulemanSori Turkey chromite concentration plant

This article reviews the major process flow sheets in practice for the recovery of chromite values from various types of ores and critical issues related to chromite ore beneficiation The comprehensive condensation of pertinent facts is intended to provide a single reference source rather than the reader perusing many articles

Sep 04 2017 · THE Philippines is the fifth most mineralrich country in the world for gold nickel copper and chromite It is home to the largest coppergold deposit in the world The Mines and Geosciences Bureau MGB has estimated that the country has an estimated 840 billion worth of untapped mineral wealth as of 2012 About 30 million

Case Study Chromite mining and health concerns 5 Chromium mining and processing In nature chromium is found as chromite ore composed of elemental iron oxygen and chromium FeOCr 2 O 3 12 heavily in about a 700 m vicinity around the Countries with commercially significant chromite mines include Russia South Africa Zimbabwe Turkey the

Some amounts of magnetite and chromite exist in the ore together with sulphide and oxide type nickel minerals The ore sample contains 132 Ni 1079 SiO 2 7839 Fe 2 O 3 13 gt Ag and 10 gt Au The ore sample is constituted of about 70 magnetite 15 sulphide minerals and 5 chromite and iron oxides as well as 10 gangue minerals

What is Chromite Chromite is an oxide mineral composed of chromium iron and oxygen FeCr 2 O 4It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromitebearing rocks are altered by heat or weathering

Jul 18 2013 · However a chromite concentrate with 46·22Cr 2 O 3 grade and 66·1 wtCr 2 O 3 recovery was obtained by the combination of shaking table and MGS It was clearly demonstrated that MGS is an ideal beneficiation equipment for fine fractions of a low grade Cr 2 O 3 ore Based on the experimental results a principal flowsheet for the enrichment

The Zambales ophiolite of western Luzon Philippines exposes a typical succession of basalt flows diabasic dikes gabbro and tectonized harzburgite The age established by limiting strata is late Eocene Lack of evidence of thrust faulting and the general domal disposition of the lithologie units indicate that the ophiolitic rocks are exposed by uplift
