However, different types of soil minerals hold and retain differing amounts of nutrients.Therefore, it is helpful to know the types of minerals that make up your soil so that you can predict the degree to which the soil can retain and supply nutrients to plants.There are numerous types of minerals found in the soil.
There is an abundance of low-grade hematite ores such as anshan-type hematite ores distributed in different regions in china.However, low-grade hematite ores cannot be used directly in blast furnaces because of their low iron minerals content, which are associated with quartz and other gangue minerals yu et al.
The uses and properties of the mineral barite.Barite occurrence.Barite often occurs as concretions and void-filling crystals in sediments and sedimentary rocks.It is especially common as concretions and vein fillings in limestone and dolostone.Where these carbonate rock units have been heavily weathered, large accumulations of barite are sometimes found at the soil-bedrock contact.
Environmental benefits.Reduces a waste disposal problem e.Less piles of rusting cars and reduces environmental problems in general.Any reduction in landfill waste sites is a blessing on the environment, so this is now a real drive to recycle metals, plastics, glass and paper.
