A basic guide to particle characterization

Many particle sizing techniques are based on a simple 1-dimensional sphere equivalent measuring concept, and this is often perfectly adequate for the required application. Measuring particle size in two or more dimensions can sometimes be desirable but can also present some significant measurement and data analysis challenges.

Particle Size Estimation and Distributions - ScienceDirect

Whichever method of measuring particle size is used, the characterization of a sample according to size is referred to as a size analysis. A size analysis in mineral processing is primarily used to obtain quantitative data about the individual size and size distribution of particles in the process stream.

Mineral processing | metallurgy | Britannica.com

Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of …

Metallurgy & Mineral Processing - SRK

1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.

Introduction to Mineral Processing - Chevron Phillips Chemical

Particle Size. The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.
