of the Broken Hill, NSW. The concentrator was designed to produce 124,000 tonnes of lead and zinc concentrates each year. The concentrator plant included single stage crushing, with conveyors that deliver the ore to a coarse ore bin. Coarse ore is ground in a two stage grinding circuit that comprises a SAG mill and a ball mill.
The No 2 Concentrator Upgrade for Xstrata Zinc incorporated major improvements to increase operational efficiency and expand the production of zinc/lead concentrate to 8 million tonnes a year, 60% above the plant's current capacity. ... ball mills and floatation circuit to replace the existing plant and obsolete rod-and-ball grinding circuit.
The result is a zinc concentrate at 55.2% Zn, 3% Pb and 137g/t Ag and a lead concentrate at 56.1% Pb, 11.7% Zn and 435g/t Ag. The concentrates are dewatered using pressure filters. A $90 million, 18-month mill optimisation programme was completed in late 2001, involving the installation of a new zinc concentrate thickener and new 50m³ ...
The lead concentrate contains c.73% lead and the zinc concentrate contains c.49% zinc. The concentrates are stored in two separate bays before being loaded into haulage trucks for sale to smelters. The concentrator incorporates conventional grinding, classification, flotation and dewatering technology to produce separate lead and zinc concentrates.
The 5m x 6.7m grate discharge SAG mill could be converted to a 1,600,000 t/a ball mill in a future expansion. An existing ball mill and cyclone cluster were relocated from the Mount Isa Copper Concentrator for use in this plant. In addition to lead and zinc concentrates, a lead/zinc middlings product was recovered by flotation.
When the Polaris Mine went into operation in late 1981, it became the world's most northerly base metal mine.The Polaris Concentrator, housed in a unique process barge, is a basic lead-zinc concentrator where flotation is used to produce the lead and zinc concentrates.The paper describes the ""coarse lead"" flotation feature incorporated in the ...
The fine crushed ore is transported via conveyor belts to the flotation plant grinding circuit. The grinding circuit consists of an Allis-Chalmers 3.04- x 4.27-m ball mill, and a 15-inch cyclone classifier. The ball mills are filled with 38 % of their volume with 3-inch wrought steel balls used to further reduce (grind) the ore size.

As a result, the Mount Isa lead–zinc concentrator was forced to produce a bulk concentrate from the beginning of 1986 until late 1996. Bulk concentrates cannot be treated in electrolytic zinc smelters, ... For comparison, the power intensity of a ball mill is about 20 kW/m 3.
The lead circuit is on the left and the zinc circuit is on the right. THICKENING AND FILTERING The silver-lead concentrate (including the unit cell concentrate) and the zinc concentrate are separately treated through wet cyclones to remove the coarse sulfides as thick underflow products suitable for direct filtration.
In mining industry, we ususally use mining ball mill for grinding the ores, like cooper ore, gold ore, lead and zinc ore, antimony ore, silver ore, iron ore, bauxite, Lithium ore, graphite, flourite ore, etc.. The crushed ores will be feeding into the ball mills. Ball mills will grind the crushed ores to be powder in proper size.
The mill consists of a single stage crushing, single stage closed circuit grinding, flotation of a copper concentrate in the unit cell, flotation of copper-lead-silver concentrate, and flotation of a zinc concentrate. The bulk copper-lead-silver concentrate is then subjected to reflotation using cyanide to depress the copper and float the lead.
