The State Government invites offers for taking up mining projects in all these untapped and under-tapped potential minerals.
Mineral Resources & Prospects
The state stands 2nd in the Mica deposits and production in the country. The Nellore Mica schist belt is known as the 2nd biggest mica belt in the country extends over a strike length of about 90 KM and covering an area of about 1000 Sq.km is found around Gudur, Rapur and Atmakur Mandals of the Nellore district. This mica belt is the repository of Muscovite mica, Quartz, Feldspar and vermiculite. Other Deposits of Mica are located in Khammam, Krishna, East and West Godavari, Nellore and Visakhapatnam Districts. The State contributes substantially to the production of Phlogopite & Muscovite Mica. At present bulk of the Mica production comes from Nellore and Visakhapatnam Districts. The book Mica, scrap Mica and Mica Powder are mostly exported due to lack of Mica based industry. There are opportunities for investment in development and establishment of manufacturing units for value added Mica based products.
Huge reserves of Barytes are found in Cuddapah, Prakasam and Nellore districts. World's largest single deposit with an estimate reserve of 70 million tonnes Grey Barytes occurs in Mangampet, Cuddapah district. In addition to these, there are number of snow white and white vein type Barytes occur in Khammam, Prakasam, Ananthapur and Kurnool districts, containing BaSo4 77 to 92% and specific gravity ranges from 3.6 to 4.21. Mangampet Barytes with grade 92% BaSo4 and an average specific gravity of 4.21 is used in oil & gas well drilling. The other grades are catering the needs of Chemical and Paint industries. The Mangampet low grade Barytes is amenable to beneficiate high grade ore to specific requirement and recovery of by-products.
Andhra Pradesh is the leading producer and contributes about 90% of the total country's production. APMDC exploiting the Mangampet deposit under public sector producing about 5 to 6 lakh tonnes per annum and intends to increase the production level to 1 Million Tonne in the coming years. Drilling fluids dominate consumption of world barytes to the extent of 90% of the total production. Most of the production form the state is being exported to USA, Middle East including Saudi Arabia, Oman and UAE, Japan and South East Asia and Eastern Europe after catering to the requirement of ONGC. The Barytes is not reclaimed or recycled for use in other wells due to low cost. The demand for useage of the Barytes in the oil well drilling is increasing with exploration activity.
APMDC is the largest producer of Barytes and intends to increase the production level to one million tonnes through joint sector participation for integrated project covering Maximization of production, beneficiation of low grade Barytes, setting up of Barytes based industries to create value addition and maximization of exports.
Potential Monazite beach placer deposits are found all along the coastal stretch right from Srikakulam district on north to Prakasam district in south and also along the Godavari, Krishna, Nagavalli, and Vamsadara river channels & confluence, which contains Illmenite, Monazite, Zircon, Rutile, Garnet and Sillimanite, out of which Zircon & Monazite are atomic minerals and classified. Illmenite & Rutile are Titanium bearing minerals. The concentration of these minerals are variable ranging from 15 to 20% in the sands, which are economically viable for commercial exploitation. The Geological Survey of India and Atomic Mineral Division have carried out investigations and explorations led to delineation of 16 potential Heavy Mineral Beach Sand Deposits over a cumulative length of 320 KM with an average width of ranging between 128 m and 1150 m from Ramayyapatnam (Nellore dist) in the south to Donkuru (Srikakulam dist) in North with heavies ranging from 20 to 32%.
Generally, beach sands are also called heavy's, even 4% of heavy's are being mined and separated through Gravity process and different mineral components are being used for different purposes, Monazite & zircon in atomic energy, Rutile & Ilmenite for extraction of Titanium, manufacture of super alloys and also as pigments and abrasive, Silliminite in refractory and Garnet in abrasive industry.
The beach sands form the main source of Garnet, Sillimanite, Titanium and manufacture of vast number of down stream products useful in various industries. The vast potential of Monazite sand deposits can sustain large scale industry over longer period for manufacture of Titanium- Di-Oxide and down stream products.
Monazite deposits being classified under atomic mineral category, State Government can take up this issue with the Atomic Energy Department, Atomic Mineral Division and Indian Rare Earth's Ltd. for taking up exploitation and processing of these vast stretch of deposits under joint venture with APMDC and manufacture of down stream products with foreign equity participation.
