Size recovery curves of minerals in industrial spirals for

Oct 15, 2014· The recovery of 0.04 mm iron particles is close to 40% while this size fraction accounts for 12–17% of the iron contained in the spiral feed (Bazin et al., 2014). This low recovery of fine particles is partly responsible for the iron losses in the plant tailings.

Observation of iron ore beneficiation within a spiral

Feb 02, 2016· A bulk sample of iron ore from the Mount-Wright Mine in the Labrador Trough (Canada) was used to prepare representative samples for the different spiral tests. The ore was sieved to remove the fraction larger than 850 μm (initially 7% of the total) to ease recovery of the large tracer at the end of each test run, and to reduce blockage of the

WASH WATER OPTIMIZATION ON AN IRON ORE SPIRAL

Spirals concentrators are one of the gravity concentration equipment used for beneficiation of minerals. Spirals are typically used for processing of fine minerals (-1mm) size fraction. The main operating variables for a spiral concentrator are the feed rate, the solid concentration, the wash water

The Effect of Particle Size Distribution and Liberation

Oct 27, 2020· Spirals, the most common equipment for the separation of heavy minerals such as chromite, are greatly affected by size distribution and the liberation degree (hence the specific gravity and size) of the feed particles. In this study, the efficiency of spirals in separation of low-grade chromite particles has been investigated by studying the distribution of grade, size distribution and

In the primary grinding stage of the flow sheet in Figure 9.14, the ore is first ground down to about 60% -75 μm and then classified into two size fractions, a coarse size fraction and a fine size fraction. The coarse size fraction is treated with spiral separators to recover part of the final iron ore concentrate.

Beneficiation of Fine Iron Ores using the Desand Process

Description. The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens.
