The WPI for minerals (base 2011-12=100) stood at 197.2 for the year 2021-22 and the corresponding index was 164.9 for the year 2020-21. The minerals included in the wholesale price index are bauxite, chromite, iron ore, copper conc., lead conc., garnet, zinc conc, manganese ore, limestone, phosphorite and sillamanite.
The nickeliferrous chromite ore overburden of Sukinda, Orissa, contains about 0.55% Ni, and forms an important resource for nickel in India. This deposit has hitherto evaded exploitation because of its lean grade and complex mineralogy.
Odisha is the largest and almost the sole producer of Chromite in India. Chromite is the only economic ore of chromium which is an oxide of iron and chromium which is used in chrome plating and alloying for the production of various materials such as corrosion-resistant superalloys, nichrome, and stainless steel etc.
The beneficiation studies of Suresh et al. (1981), concludes that low grade chromite ore of 16–25% Cr 2 O 3, of Sitampundi area of India, cannot be upgraded by using tabling and flotation techniques, to meet the metallurgical grade due to the intimate association of iron in the lattice of chromite.

Chromite is an iron chromium oxide mineral and the only ore of chromium metal. Chromite is a metal used to induce hardness, toughness and chemical resistance in …
Forty percentage of Indian chromite reserves are suitable for metallurg ical use (Cr:Fe>2.8), 33% for refractory making (Cr:Fe of 2.8-1.8) and 27% fo r chemical industries (Cr:Fe <1.8)[1-2 ]. There is heavy demand for metallurgical grade chromite ore due to rap id growth o f steel industry and limited availability of such high-grade ore resources.

1. Introduction. Chromite ore processing residue (COPR) is a waste of the chromate (CrO 4 2−) extraction roasting process and is still deposited in the environment in large amounts in some newly industrialized countries.In the past, the waste has been produced in several industrial areas, such as Glasgow, Scotland (Farmer et al., 1999) …
In the present study, we present the occurrence and emplacement of chromite ore deposits from two abandoned mines (Kankavali [Janoli] and Wagda) in the Sindhudurg district of Maharashtra, India. These ores, that occurred as lenses and are associated with metamorphic and ultrabasic rocks, consist of octahedral grains of …
Notably, many of India's chromite deposits exhibit ferruginous characteristics, marked by the prevalence of iron-bearing gangue minerals alongside chromite.
