rule of thumb mineral processing

Hard Rock Miner's Handbook

Long before science and engineering evolved, Rules of Thumb constituted the sole body of mining knowledge. In 1891, the Royal Commission on mineral resources in Ontario, Canada stated that we had been "mining by rules of thumb for long enough." The Royal Commission probably never imagined that over 100 years later we not only continue to employ

important lithium ore mineral. A typical run of mine ore can contain 1-2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). Higher grade concentrates with 7.6% Li 2 O and low iron content are used in ceramics and more demanding industries.

Mineral Processing / Metallurgy Rules of Thumb

Here is a list of General Rules of Thumb often used in Mineral Processing and Metallurgy: A concentrator (mill) requires up to 3 tons of water for each ton of ore processed. It is therefore important to operate with the maximum practical pulp density and minimum practical upward or horizontal movement. The basic philosophy requires movement
