Typically, samples of ore of a relatively large mass are taken. These samples are crushed to reduce the particle size and sub-samples of the crushed product taken. These in turn, may be further reduced in particle size and sub-sampled again in successive stages until there is a sample that is submitted to the laboratory for analysis.

mass of material it is necessary to know both the particle size distribution and also the shape factor of the particles. The particle size gives one dimension that can be called the typical dimension, D p, of a particle. This has now to be related to the surface area. We can write, arbitrarily: 3V p = pD p and A p = 6qD p 2 where V p

and size classify the feed through multiple size reduction steps (grate, trommel and hydrocyclone). The small aspect ratio (L/D ~ 0.5) and use of pulp lifters allows for the immediate removal of up to 35 % of the fine solids (< 2 mm) from the crushed feed. Lateritic bauxites are usually classified
The samples were crushed to various top sizes between 12 mm and 50 mm and a particle size distribution was performed by screening batch-wise using a Rhologan sieve shaker. Modified one-dimensional compression tests were performed to assess ore compression behaviour under load as described by Lupo (2011) .

Authors classified the particle sizes into small size (0–10 mm), medium size (10–20 mm) and large size (20–30 mm), and adopted the average size (0–30 mm) as the control group. To make the reference of each group more reliable and reduce the error, the average gradation was tested in each group.
The particle size analysis with the Cilas 1190 was performed from the samples divided equally into small fractions by a rotating sample splitter, and the particle size was determined from a slurry that contained 1:10 ore in distilled water. The slurry was incubated overnight in water on a shaker for both ore types.

Laboratory Hydrocyclone Testing Equipment. In the past, mechanical classifiers were usually selected to operate in closed circuit with grinding mills. These devices require much floor space and have been essentially replaced in large plants, as well as small, by hydrocyclones. Since classification is a potential plant bottleneck, it is ...
AS a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant.
Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.

Section snippets Crushed ore agglomeration. Crushed ore agglomeration has two major aims. First, it is the best opportunity for the thorough application of the leaching solution prior to building the heap and "kick starting" the leaching process itself (Bouffard, 2005, Dhawan et al., 2012a, Kodali et al., 2011a, Purkiss and Anthony, 2004).
