for a given ratio of reduction the type of crusher with a flared crushing chamber will usually deliver a cleaner product than any of the older types conversely more reduction can be performed in the machine without creating excessive fines. the facts outlined in the foregoing paragraph have an important bearing on crushing plant design.
calculation of reduction ratio in crushing [image (135 5 3)] crushing equipment the selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).

the 80% passing size in microns is a convenient term for expressing the fineness of a crushed or ground product. it is also a convenient base for calculating the reduction ratio and the work required for reduction. it is readily found by plotting the percent passing on log log paper as in fig. 5 to determine the size distribution curve.
extracting copper metals are found the copper ore has to be dug from the ground. the ore contains some copper mineral and lot of waste rock. the copper mine in picture 4 produces 6 tonnes of copper from every 1000 tonnes of ore. extraction an ore has to be changed chemically into the metal. this process is called reduction. how this is

smelting is a process of applying heat to ore in order to extract a base metal.it is a form of extractive metallurgy.it is used to extract many metals from their ores including silver iron copper and other base metals.smelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind.
copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes which will ultimately be made into products for everyday use.the most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
