What is Lead Ore and How to Crush?
Grinding. Ball Mill or SAG Mill: The crushed ore may then be fed into a grinding mill to reduce the particle size to a powder form. Separation. Flotation or Gravity Separation: The fine lead ore particles are then subjected to a separation process to concentrate the lead content. Flotation is commonly used for this purpose, where chemicals are added to a slurry of ground …
