Basicity (in metallurgy), the ratio (in percent by weight) of basic and acidic oxides in iron ore materials (iron ore, sinter, and pellets), and also in blast-furnace and steel-smelting slag. Basicity defines the chemical composition and metallurgical properties of such materials. In the simplest case, basicity is defined as the ratio of CaO to SiO2 or of the total of CaO and MgO to that of SiO2 and Al2O3. The processing of iron ore materials requires the calculation of natural basicity and the basicity produced by the addition of flux. Basicity may vary from several tenths of a unit to 2–3.

Patient discussion about basicityQ. what are the basics products we as a humans, need to have in our diet? A. A regular healthy diet should be comprised of a 40-50% carbohydrate (bread, rice, etc.), 30-40% protein (dairy, meat, chicken, fish) and 20% fat. Other important ingredients are fruit and vegetables, that contain large amounts of fibers and vitamins. Q. How do i keep my self fit and healthy? what are the basic things i should and need to do in order to achieve a goal like this ? A. from research they did they found out that in a long term doing regular physical activity will not change life span. but they did discovered that it dramatically changes the quality of this life. here is a wonderful guide (pdf file) how to stay in shape for adults: http://www.health.gov/paguidelines/pdf/adultguide.pdf
