Chromite an overview ScienceDirect Topics

Chromite (Cr) occurs exclusively in mafic and ultramafic igneous rocks (Papp and Lipin, 2006).Although some Cr-based minerals such as crocoite (PbCrO 4), vauquelinite (Pb 2 Cu[CrO 4][PO 4]), uvarovite (Ca 3 Cr 2 [SiO 4] 3), and merumite (4(Cr,Al) 2 O 3 3H 2 O) are well known, chromite (FeCr 2 O 4) is the only one that is a commercially recoverable Toxicological assessment of CMQW generated due to chromite mining activities at Sukinda Valley has revealed high chromium contamination along with Zn and Fe. The present study focused on the mechanism of chromate reduction by an indigenous multi-metal tolerant bacterium, Rhizobium pusense CR02, isolated from CMQW.

The Philippine mining industry: status and trends in mineral

Abstract. The mining industry sector is a major backbone of the Philippine economy. The long history of the industry has been much affected by the vicissitudes of the international market, as well as other domestic factors. With the adoption of the 1986 Constitution, the concept of awarding mineral rights has been drastically changed fromIncreasing population levels, growing economies, rapid urbanization and changes in consumption patterns have increased the demand for raw materials such as base and precious metals, leading to growing concerns regarding their availability and the global efficiency of the mine supply chain.
