Hard Rock Mining vs. Placer Gold Mining

Hard rock, or “Lode” gold is still contained within ore, and various methods are used to extract the metal from the rock that surrounds it. Placer gold on the other hand occurs when natural erosion has released the gold from its host material and the gold is now a separate piece, whether that be a small speck of gold dust or a large gold nugget.

Particle Analysis in Mining and Minerals HORIBA

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
