Results and Disscussion. In-stream mining of sand, gravel and gold in the area has led to the re-suspension of sediments in the water causing the brownish colouration of the water and this water is been consumed by the miners in the area due to lack of alternative source for drinking water ( Figure 6 ).
It does not apply to you if you mine gravel from streams for personal use or you are a political subdivision (for example, county, city) using your own equipment and personnel, and are mining the material for your own use, or you are removing sand from the Missouri or Mississippi rivers.
Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.
Equipment must be able to sustain brutally cold winters, abraisive silica sand, sticky bitumen and unstable ground conditions. Although the very first commercial oil sands mining operations used technology borrowed from the coal mining industry, operators have long since evolved to truck and shovel mining, which is much more efficient and cost effective.

Concerns have been raised regarding environmental and nuisance problems as sand mines proliferate. Mine siting is regulated at the local zoning level. Mine reclamation plans, required by NR 135, must be in place before mining begins. The Department of Natural Resources provides technical assistance to local authorities for these plans.
Mineral production: all minerals obtained from a series of extraction activities which make them marketable. It should be mentioned that in some mining activities, minerals are supplied to the market without undergoing dressing process, whereas in others, minerals are supplied to the market after a series of physical and/or chemical treatments for separating some of the waste from ores, separating
