Abstract The Gomati and Nea Roda ophiolites are located into the Serbo-Macedonian massif of Chalkidiki peninsula (Northern Greece). present work focuses on variability platinum-group elements (PGEs), geochemistry, spinel mineral chemistry, minerals (PGMs) — base metal (BMMs) assemblage in chromitites three localities (St. George, Tripes, Limonadika) Roda. studied show variable textures heavily ...

OBJECTIVES The aims of the study were to describe the noise levels at an open cast chromite mine in Odisha, India, and the hearing threshold of its workers and to associate their hearing loss with their age, work station and length of employment at the mine. METHODS We performed a cross-sectional study of the hearing threshold of chromite mine workers. Audiometric data from 500 subjects was c...

Examination of published procedures for the decomposition and subsequent analysis of chromite and chrome ores shows some to be unnecessarily complicated and time consuming. Others fail to yield consistent and reproducible results. Decomposition is rapidly and effectively accomplished using the peroxide frit technique of Rafter. Chromium may then be removed and determined volumetrically allowing...

Chromite ore processing residue occurs at over 130 sites in Hudson County, New Jersey. Many of these sites are in urban residential areas. This waste is a result of 70 years of chromate and bichromate chemical manufacturing. At least 15% of the sites contain total chromium concentrations greater than 10,000 mg/kg, with hexavalent content ranging from about 1 to 50%. Continuing leaching of this ...
