Performance evaluation of MG6 spirals in a cassiterite concentration circuit

Abstract

Cassiterite is the main mineral from which tin is extracted, and its efficient separation is essential for the economic success of mining operations. Spiral concentrators are critical equipment in cassiterite processing. This equipment uses centrifugal force to separate dense particles, such as cassiterite, from gangue minerals. Optimizing cassiterite processing is crucial to increasing the efficiency and profitability of mining operations. This study presents the results of replacing the primary and secondary spirals of the rougher (model LG7) and scavenger (WW6E triple pitch) stages with the new model MG6. The results obtained show that there was an increase in Sn enrichment in the primary and secondary rougher stages but a decrease in recovery in the scavenger stage, highlighting possibilities for adjustments in the circuit.
