  • Chinese company Bosai Minerals is an established key producer of refractory-grade bauxite from its mines at Linden, Guyana, and has reserves of 186m tonnes. Production of calcined bauxite is in the order of 250,000 tpa and the company also produces another 150,000 tonnes of chemical and cement bauxite grades. Production levels suffered in 2012 owing to a period of unrest in Linden, and the mine and plant were closed for around a month, reducing production levels by around 20,000 tonnes. Since then, Bosai has reaffirmed its commitment to producing bauxite and investment in Guyana.

    Minerao Varginha is a bauxite producer with mines in Pocos de Caldas (MG) and two bauxite processing facilities, one in Fazenda Varginha Andradas and the other in Eletro Varginha Caldas, both in Minas Gerais. Bauxite reserves are 40m tonnes. The company is investing R$23m ($12m) in a new mine in the region of Manhuau/Cataguazes to produce an additional 50,000 tonnes of washed bauxite. Varginha's total bauxite production in 2011 was 310,000 tonnes, along with 100,000 tonnes of manganese and 120,000 tonnes of clays.

    GMD mines low-grade, non-metallurgical bauxite at Bhatia in the Saurashtra district of Gujarat, and high-grade material at Ratadia in Kachchh district. The Ratadia mine provided high-grade material for the company's 50,000 tpa Gadhsisa bauxite calcination plant in the Kachchh District, in Gujarat, which is the largest single rotary kiln bauxite calcination plant in India. The plant was refurbished in 2007, although it closed at the beginning of 2010 because of there was no "plant-grade" bauxite available as feed. Sales of calcined bauxite in FY 2009-2010 were 18,000 tonnes, which fell to 5,000 tonnes in 2010-2011, as stocks were sold.
