The Masinloc Chromite Operation is located in the province of Zambales in the Philippines. It was initially discovered in the year 1925, making it a historically significant mining site. Geologically, the area is characterized by the presence of dunite, which is a type of ultramafic rock. Dunite is believed to have formed during the Upper ...
The Acoje block of the Zambales ophiolite in the Philippines is a fragment of forearc lithosphere that formed at ca. 44–43 Ma during subduction initiation in the Western Pacific (Fig. 1 A; Hawkins and Evans 1983; Leblanc and Violette 1983; Yumul and Balce, 1994).This block hosts a world-class high-Cr chromite deposit with Cr reserves of ~25 …
Chromite is the most important chromium ore mineral. It forms a complete solid solution series with many other members of the group, eg. in the Chromite-Hercynite Series, Chromite-Spinel Series, Chromite-Magnetite Series and the Chromite-Magnesiochromite Series.It is the iron analogue of Zincochromite, Cochromite, Manganochromite and …

1. Introduction. A lot of information has been generated for the surrounding oceanic marginal basins of the Philippines (e.g. Dimalanta et al., 2002; Hickey-Vargas, 2005; Li et al., 2005; Zhu, 2007).This has been made possible through the different offshore studies (drilling, dredging, marine geophysics) that have been done in these areas coupled with …
As a result of the removal of Mg and Si from the ultramafics, chromite has been enriched in the lateritic soils by a factor ranging from 2 to more than 10. In some areas, soils of different ultramafic rocks are mixed due to alluvial processes which can cause further enrichments of chromite. These mixed soils often occur as transported soils ...
The chromitite-bearing peridotites of the Zambales mafic-ultramafic complex form the lowermost level of the Zambales ophiolite, which exposes a complete ophiolitic sequence. The chromitites occur close to the peridotite/gabbro transition zone.The chromite orebodies are structurally classified into three major types: (1) concordant tabular deposits, (2) …

The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 3:1 or over, 17.6 pct having a ratio between 2:1 and 3:1, and 30.4 pct having a ratio less than 2:1. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1.

Mining of metallurgical-grade chromite ore began in the Philippines at the Acoje mine in 1933, and four years later mining started at the giant refractory*.grade chromite deposit at Goto, near Masinloc. From 1933 to the end of 1964, Philippine production of both ore types is believed to have totaled approximately 9,800,000 metric tons (m.t.).
The Acoje block of the Eocene Zambales ophiolite (NW, Philippines) is a fragment of forearc lithosphere in the Western Pacific and hosts a world-class chromite deposit.
