Unless you are only doing civil works, there generally can’t be Mining Engineering without Mineral Processing Engineering for the majority of hard-rock ores we mine needs further processing before the metal it contains can be used as it is how minerals extracted from ores.   Most valuable rocks go thru multiple steps of process-operations starting with […]

Mineral Processing / Metallurgy Rules of Thumb

rule-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 over the […]

Grinding Rule of Thumb

Grinding

Here is a list of Rules of Thumb often used in Grinding Circuits: Fine ore bins (or stockpiles) that provide feed to the grinding circuit should have a capacity equal to 30 hours of processing. Source: Northern Miner Press Grinding is a low-efficiency, power-intensive process and typically can account for up to 40% of the direct operating […]

Froth Flotation Rule of Thumb

rule-of-thumb

Here is a list of Rules of Thumb often used in Froth Flotation: Clean metallic gold particles (free gold) finer than 200 microns (65 mesh) float readily with appropriate reagents. Gravity separation is desirable for larger particles. Source: Mining Chemicals Handbook (Cyanamid). When designing the flotation circuit for a proposed mill, the scale-up factor for flotation retention times […]
