Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it 11.24 Metallic Minerals Processing,The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/Fruitfulium ores, require little or
In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock. Secondary crushing and screening can result in further classification and grading of iron ore.(PDF) Screening and Sieve Analysis Ithuteng Khoza,Screening usually follows after comminution. The aim of this experiment was to screen and sieve haematite ore and to study its particle size distribution. The screening was done using an industrial screen and the sieving was done using laboratory Tyler sieves. The initial mass of the ore manually fed to the screen was 11.965 kg.
