As recovery on the spiral trough is a function of mass yield and grade, the ultra-fine 7 spiral had a better recovery than the HX5. This makes the UF7 an ideal rougher spiral. Spiral separators for the recovery of ultra-fine particles have a unique profile, pitch and features to ensure it performs efficiently.

The spiral separator is suitable for processing alluvial gold ore, especially for gold ore with a high degree of monomer dissociation and flat shape. Besides, it is also good at dealing with fine gold ore with particle sizes between 0.003-0.6mm containing low mud content. Spiral chutes are often used for rough concentration. What we love:

New model spiral separators have now been developed that are specifically designed to treat material finer than 0.1 mm. Design features are discussed and performance data on a variety of ore types are presented to illustrate the effectiveness of gravity separation on material below 0.1 mm in size using fine mineral spiral separators.

The installation in 1948 of a Humphreys spiral concentrator section at the Hill-Trumbull plant of The Cleveland-Cliffs Iron Co. is the latest commercial method on the Mesabi Range being used for the recovery of fine iron ore. In two stages of concentration 84 spirals treat approximately 120 long tons per hour of minus 1/8 in. ore.

The spiral separation process has also caused − 45 μm particles to have a higher grade than other size fractions. 3.2 The Effect of Particle Size Distribution on Spiral Chromite Recovery. Under steady-state operating conditions for spiral separators, the particle size distribution of the feed is a significant parameter in its efficiency.

Iron ore concentrate suitable for pelletisation was also produced using multi-gravity separator (Rao et al. 2018). Beneficiation of iron ore slimes to produce a concentrate suitable for pelletisation using spiral concentrator in a single step was tried successfully in this attempt.

Spiral separator, SLon separator, and reverse flotation flow sheet to process an oxidized ore. In Fig. 9.14, the feed ore is first ground down to about 60% −75 micron particle size in the primary grinding stage of the flow sheet, and then classified into two size fractions, a coarse size fraction and a fine size fraction.

Available in single or double separators. Hoffman Heavy-Duty Double Spiral Separator offers quality construction, welded, galvanized steel to withstand heat and vibration and both direct and hopper feeds. Four separating turns are standard, with fourteen flight sizes available from one and a half to eight inches.

Working principle . Raise the spiral chute and fix it in the proper position, sand pump transport the ore to the feed inlet, adding water to adjust the concentration of the slurry. The slurry naturally swirls from high to low, and generates an inertial centrifugal force in the rotating bevel flow rate.
