Bedrock refers to the solid rock that makes up the Earth''s outer crust. Weathering is a process that turns bedrock into smaller particles, called sediment. Mechanical weathering includes pressure expansion, frost wedging, root wedging, and salt expansion emical weathering includes carbonic acid and hydrolysis, dissolution, and oxidation.

Hard Rock Lithium Deposits

2021-4-15 · Hard rock lithium deposits are generally mined by the open pit method. Blocks of mineralized pegmatite are crushed, milled, and then sent to flotation cells, where ore minerals are separated. At about a concentration of 5-7% LiO 2, ore is sent to a plant to be chemically processed to produce lithium carbonate apter 4 Engineering Classification of Rock MaterialsThe rock unit is the basic mapping unit for the rock material field classification (RMFC) system.
