Barite Mining Industry
Barite is a mineral ore that is naturally occurring and is barium-based. Barite has a high density and is chemically inert but is relatively soft. Barite is explored in various regions all over the world, in various colors and deposit types. Its chemical and physical

properties have found its wide-ranging applications in various industries, which has led to a surge in demand for barite mining.
Based on the type of mine, the market is classified into open-pit and underground. The open-pit segment accounted for the major share of the market, and it is anticipated that it will maintain its attractiveness during the forecast period, as they provide greater recovery of the barite ore due to the increased maneuverability using heavy machinery. Open-pit mining is also a safer alternative to underground mining.
Based on the grade, the global market is classified into up to grade 3.9, grade 4.0, grade 4.1, grade 4.2, grade 4.3, above grade 4.3. The grade determines the purity of barite by measuring the specific gravity of the barite based on the concentration of barium sulfate present in the ore. Different grades have different applications. The grade 4.2 segment accounted for the major share in the market. Grade 4.2 barite has a specific gravity of 4.22 g/cm3 and is the most found grade in explorations and finds its use in fluid drilling applications. Based on the deposit type, the market is classified into residual, bedding, vein, and cavity filling. The bedding segment accounted for the major share of the market, and it is anticipated that it will maintain its attractiveness during the forecast period. It is the most widely used barite, used in oil well drilling, and is grey in color.
Due to the increased industrialization and urbanization, there has been a surge in energy consumption all over the world. This has given rise to increasing crude oil explorations and mining, which requires barite as a weighting agent in drilling processes. This increase in demand for barite is likely to drive the global barite mining market during the forecast period. The key market restraint for the market is the rising awareness of the negative impacts of barite mining on the sulfate levels in the groundwater. The sulfates tend to act as laxatives in water and give it a bad taste and odor, which is affecting the growth of the market.
INDIAN RICE BRAN OIL INDUSTRY Introduction In India rice is not just a crop, it’s country’s economy. India is the world’s second largest producers of rice with approximately 43 million hectare planted area, accounting for 22% of the world’s rice production, it is mostly grown in the eastern and southern parts of the country. Rice being member of tropical C3 plant it flourishes well in hot and humid climate. In India rice is mainly grown under rainfed situation where annual rainfall is ranges from 1000-2500 mm. Therefore, it is fundamentally grown as kharif crop in India however, it is also being cultivated in rabi and summer season based on the water availability. If we see the journey of rice around the world, it has been slow, but if it establishes its roots, crop stayed and became integral part of agriculture and economy of that locality. In the Indian subcontinent, more than a quarter of the cultivated land is under the rice crop. It makes essential part of the daily meal in the southern and eastern parts of India, whereas in the northern and central India, wheat is common food stuff, nevertheless, rice holds its own importance and is cooked daily at least once. Hence, demand for rice is increasing year after year. At present, rice is being grown in 43.79 million hectare and producing 117.47 million tons annually with the average productivity of 2578 kg/ha (GOI, 2020). Milling is a crucial step in post-production of rice. The basic objective of rice milling system is to remove the husk and the bran layers, and produce an edible, white rice kernel that is sufficiently free from impurities. Rice being the indispensable source of energy to the huge group of Indian population, upon it milling we also generate huge amount of rice bran. Based on the country’s paddy production, rice bran output potential is about 9.8 million tonnes annually (Solvent Extractors’ Association, 2019), However, at present India is processing only 5 million tonnes out of 9.8 million tonnes which is just half of its total potentiality and the rest is consumed directly as cattle feed. The rice bran oil production potential is over 1.62 million tonnes per annum in India as against untapped potential of nearly 6.5 tonnes (Solvent Extract Association, 2019). However, a study conducted by Zúñiga-Diaz et al., (2017) for quality profiling of rice bran oil indicated that, rice bran has 21.44% of raw oil, with a chemical composition of 48.48% oleic acid, 35.26% linoleic acid and 14.54% palmitic acid, as well as a free fatty acid content of 8.15%. On the other side if we see the scenario of vegetable oilseeds in India, Oilseed crops stands next to the cereals and plays a key role in deciding agricultural economy. The so called “Yellow Revolution” happened during 1986-87 brought self-sufficiency in oilseeds but was not sustained for a longer period of time. This could be due to huge gain in population followed by tremendous shift in the fat consumption pattern (Fig 1). At present, India need to produce about 25 million tonnes of edible oils to meet its domestic requirement at the current consumption level of 19.4 kg per.
