Utkal Alumina International to expand Baphlimali Bauxite Mining Project in located in village(s) Paikkupakhal, Karanjkupakhal, Dhuturapas, Dandabad, Chandragiri, Durumusi, Suryagada and Kendumundi, Tehsil(s) Kashipur & Thuamul Rampur, District(s) Rayagada & Kalahandi in Orissa. The project involves opening a new mine for production of bauxite to 8.5million tonnes per annum (million TPA) to meet the captive requirement of their alumina plant located at a distance of about 17km. The total project cost is estimated at Rs. 3000 million. Approximately 24,650TPD of mineral will be transported through a 21km long covered conveyor. The Baphlimali Plateau forms a part of Eastern Ghat Hills and the topography of the area is a plateau top generally flat and the elevation above mean sea level ranging from 990m-1093m AMSL. It has been reported that the plateau top is devoid of vegetation in most part giving a bald look to the area (Khondalite exposures, however, support growth of trees and shrubs). The ultimate working depth of mine will be 1054m AMSL(40m from the plateau top of 1094m AMSL) and 960m AMSL(30m from plateau top of 990m AMSL). The ground water table is reported to vary from 890m AMSL (100m from the plateau top of 990m AMSL) to 944m AMSL(150m from the plateau top of 1094m AMSL). The mine working will not intersect the ground water table. The peak water requirement of the project is estimated as 2000m3 per day, which will be obtained from the surface water(San River or Kandabindha Nallah).
Brahmani River Pellets to set up iron ore beneficiation plant in villages Tonta and Nalda in Barbil taluk in Keonjghar district of Orissa. The project involves setting up of a iron ore beneficiation plant with a capacity of 4.75miilion tonnes per annum (million TPA) throughput. The raw material will be transported through the belt conveyor and through the road. The proposed beneficiation plant will have a pipeline of 192 km length passing through two Districts namely (i) Keonjhar and (ii) Jajpur, for transport of beneficiated iron ore slurry to the pellet plant at Jajpur. The beneficiation process involves, primary wet grinding, hydro-cycloning, two stage spiral classification, single stage high gradient magnetic separation, re-grinding and thickening of concentrate received from both spirals and magnetic separators and tailings. The tailings dam will receive tailings @ 0.7million TPA from the proposed beneficiation plant. The tailings does not contain any soluble minerals. The tailing dam is impounded with hills on three sides and is almost valley and is an independent water shed with no storm water inflow from outside the pond area. The surface run off discharge from the catchment of the tailing dam join the nearby Lashkara Nallah, which meets Karo River at a distance of 6km in Northern side of the catchment.
Feegrade & Co to expand Nadidih Iron and Manganese Ore Mining Project located in village(s) Nadikasira & Rengalbera in Bonai Taluk in Sundergarh district of Orissa. The proposed rated capacity of the mine is to be expanded from 48,000 tonnes per annum (TPA) (0.048million TPA) to 2.6million TPA. The total project cost is estimated at Rs. 98.0 million.
National Aluminium Co to expand Panchpatmali Bauxite mine located in village Damanjodi, Tehsil Pottangi in Koraput district of Orissa. The proposed rated capacity of the mine is to be expanded from 6.3million tonnes per annum (million TPA) to 6.825 million TPA to meet the additional requirement of their alumina refinery. The transportation of mineral from mine to the alumina plant will be through a 14.5km long conveyor.
Orissa Manganese & Minerals to expand Tentulidihi Manganese Ore Mining Project located in village Dengula, Tehsil Bonai, Sundergarh district of Orissa. The proposed rated capacity of the mine is to be expanded from 2,500tonnes per annum (TPA) to 25,000TPA. The total project cost is estimated at Rs. 10.0 million.
