Mineral sands are mined by surface mining methods including open cut mining, suction dredging and hydraulic mining. The first stage of the mining process is to remove all timber and topsoil from the mine site. The topsoil is stockpiled for later rehabilitation of the site after mining has been completed.
In Situ Methods used in the Oil Sands In situ methods are used to recover bitumen that lies too deep beneath the surface for mining (about 80% of the oil sands in Alberta). The success of in situ methods depends on the resolution of two major issues: 1) reducing the viscosity of bitumen so that it will flow, and 2) recovering the bitumen from deep within the earth (OSDC 2008c).

sand and sandstone. Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant.

· The Hidden Environmental Toll of Mining the World's Sand. By far the largest mining endeavor globally is digging up sand, mainly for the concrete that goes into buildings. But this littlenoticed and largely unregulated activity has serious costs — damaging rivers, wreaking havoc on coastal ecosystems, and even wiping away entire islands.
Oil sands deposits that are greater than 75 meters below the ground surface are usually extracted without removing the overlying rock and dirt. This is known as in situ oil sands mining. Oil sands deposits are usually split into two types of deposits. Shallow deposits are loed within approximately 75 meters of the ground surface and are extracted using surface mining methods.
Three parts of mine design: feasibility study, preliminary design, and construction plan. The key to mine design is all must be established on the basis of detailed investigation, and therefore Xinhai Mine Design Institute will firstly take a comprehensive field study to the mine of clients including the crude ore for dressing plant, site, water, electricity, traffic, geography, etc.
Insitu extraction methods are used to recover bitumen that lies too deep beneath the surface for mining (greater than 75 metres underground). Currently, 80% of oil sands reserves are accessible via insitu techniques. Steam Assisted Gravity Drainage (SAGD) is currently the most widely used insitu recovery method.

· Different mining methods (mechanical or manual) are adopted for the extraction of sand from these sources under dry (above water table) and/or wet (below water table) conditions. This chapter describes briefly the different sources, methods and hydrogeological bearings of sand and gravel extraction processes in river ecosystems.
