Abstract. This paper describes the use of modelling and simulation techniques in the analysis and optimisation of grinding circuits at the Lead/Zinc Concentrator of Mount Isa Nines Limited.
In the beneficiation process, the sulfide leadzinc ore is mainly flotation. Among them, the proportion of zinc ore in most leadzinc ore is higher than that of lead ore. Therefore, in the actual process, the method of "suppressing zinc and floating lead" is generally adopted. Main principles to deal with leadzinc sulfide ore.

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. Sorting of leadzinc ore
ShalkiyaZinc's greenfield zinclead concentrator in Kazakhstan becomes effective The previously announced signed contract to supply all mineral processing technology to ShalkiyaZinc, the operator of a zinc and lead mine in the Kyzylorda Region, located in the south of Kazakhstan (refer to Company Announcement No. 122022), is now effective.

The copper smelter at Mt Isa has a processing capacity of 300,000tpa. The Mt Isa operations process approximately of ore. The project is Australia's secondlargest copper producer. Mount Isa Mines operates two separate mining and processing streams, copper and zincleadsilver, near Mount Isa, Queensland, Australia.
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.
Lead and Zinc Ore Concentration If the mineral veins separate from the rock cleanly, then processing workers can concentrate the ... ore has been concentrated at a mill near the mine, the lead concentrates are shipped to a smelter. Here, in the case of galena, the first step involves removing the sulfur from the mineral. Roasting
Abstract The ore from Baiyinchagan mine is typical increasingly refractory as the mine get deeper, especially the increasing lead and zinc contents, which not only detrimentally affects the product quality of copper concentrate, but also results in the loss of lead and zinc resources In order to solve the problem, two routes were conducted: first, depress liberated lead and zinc minerals from ...

Under the agreement, FL will supply two underground crushing stations with a materials handling system to the process plant, a full package of comminution and separation equipment, including SAG and ball mills, mill circuit pumps and cyclones, the zinclead concentrate flotation and regrinding circuit, including nextSTEP, VXP vertical ...
The present lead mine concentrator was built in 1966 with rod and ball milling, leadsilver flotation, zinc flotation and lowgrade middlings recovery circuits. In 1982, MIM added heavymedium separation to preconcentrate the mill feed. Later enhancements have included column cell flotation.

Early history. Simeon Reed bought the Bunker Hill Mine and Mill, and incorporated the Bunker Hill and Sullivan Mining and Concentrating Company on 29 July 1887. John Hays Hammond was hired to manage the mine, and a new concentrator, The Old South Mill, became operational in 1891, capable of 150 tons per day. Hammond became president on 2 July 1891, followed by Nathaniel H. Harris on 15 June ...

This difference in net returns is still more apparent when zinc is considered, for zinc in a bulk concentrate is very undesirable at lead or copper smelters. You usually not only get nothing from these plants for the zinc, but are penalized for it above a certain minimum, and the amount admitted without penalty is as low as 5% in some instances.

installed at the Mount Isa Mines' Lead Zinc Concentrator in 1994. The mill, the M3000 IsaMill™, was quickly installed in other circuits at this concentrator, and was installed in the McArthur River Concentrator in 1995 (Johnson et al, 1998). Later, in 1999, it was commercialised and sold outside of the Xstrata group.
