A process and method for separation, extraction and filtration of heterogenic mineral compositions from the offshore coastal region is described. the coastal region, abutting a distance of 1 or 2 kilometer from the surface water of the sea is taken into consideration and the coastal sands occurring in this region which are rich in heavy mineral are first dredged by using suitable dredging ...
Lucknow (India) E-mail: [email protected] Introduction ¾Although, the various classes of preparations involving simple expression, aqueous hot and cold extraction and evaporation were in vogue since long time but, real and scientific rapid progress in the extraction procedures for medicinal plant's preparations was made after 19th century.
Extraction is complicated because of environmental issues. But, 'underground coal gasification', can create 6,900 trillion cubic feet of gas which is way HIGHER than shale reserves. India's shale resources at a more modest 65 trillion cubic feet. India's CBM potential is estimated at 450 tcf.
But in India, reports of sand mafias cashing in on the country's construction boom have lately been making headlines. Last month, the issue went viral — a 17-year-old named Kavya in a fishing village in the state of Kerala posted a video on a mobile phone app about how excavators and dredgers had invaded her coastal community.

Caving is the general method adopted in majority of our mines at it does not involve the high cost of stowing arrangements. For depillaring with stowing availability of stowing material at a reasonable cost is a pre-requisite. River sand is the abundant stowing material commonly used and its hydraulic conveying is the general practice.

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
