By 1650, coal and tin mining were important industries in England, and water had become a serious problem in many mines that had been worked for centuries, particularly the deep tin mines in […]

Very Small Hydrocyclones

In the early 1950s, cyclones were being used in the kaolin industry to separate the finest kaolin particles into products that could be sold at a premium. Their success gave a boost to cyclone technology and led to the design of small cyclones that could efficiently extract the very fine particles from the feed. This […]
