The rejection rate of leadzinc ore in heavy medium separation is generally 30% to 40% of the original ore. Crush More and Grind Less. It is helpful to save energy and improve the production capacity of the ball mill, and both at home and abroad are studying to reduce the particle size of the final product of crushed ore.

Semiautogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles. This research aims to analyze and compare the properties of raw ore and pebbles from a zinc and tinbearing ore. The results show that the contents of sphalerite, cassiterite, biotite, antigorite, pyroxferroite ...

Lead was recovered through a direct smelting reduction route from a lead concentrate by using mixtures of Na2CO3 and SiC to 1000 °C. The lead concentrate was obtained from the mining State of Zacatecas, México by traditional mineral processing and froth flotation. The experimental trials showed that 86 wt.% of lead with a purity up to 97% can be recovered from the lead concentrate by a ...

With most ores containing lead and zinc sulphides, the production of a separate lead concentrate for shipment to the lead smelter, and of a separate zinc concentrate to ship to the zinc smelter, makes for a profitable operation. It only gravity concentration or bulk flotation were used the ore would probably prove unprofitable to treat.
