Nov 15, 2007 In order to estimate acute-to-chronic toxicity ratios (ACRs) relevant to a coldwater stream community, we exposed rainbow trout (Oncorhynchus mykiss) to cadmium (Cd), lead (Pb), and zinc (Zn) in 96-h acute and 60+ day early-life stage (ELS) exposures. We also tested the acute and sublethal responses of a mayfly (Baetis tricaudatus) and a midge (Chironomus dilutus, formerly C. tentans) with Pb …

The concentrator has a milling rate of 70,000t/d and is the largest single-circuit SAG-milling operation in the world. The SAG mill provides feed for ball milling to produce flotation feed, with the ball mills featuring variable-speed drives to enable the mills to handle the range of different ore hardness found at Antamina.

A plant survey was carried out on the lead secondary rougher and scavenger banks of the Lead/Zinc Concentrator of Mount Isa Mines Limited. Sizing analysis of the survey samples demonstrated that a major limiting factor to overall lead recovery in this section of the plant was the diminished recovery of the fine galena in the minus 5 microns particle size fraction.

Lead is mined in association with zinc and silver. The ore is concentrated on site by crushing and differential flotation before being sent to a primary smelter. Personal and area samples for airborne lead were taken at a lead mine concentrator mill. Zinc and iron were also present in all the airborne dusts. Samplers used included the closed-face 37mm filter cassette (the current U.S. standard met

Missouri lead ores are unique because they represent the only domestic cobalt resource that is presently being mined and processed. Lead, zinc, and copper concentrates are produced from the ore, and since cobalt is detrimental in these products, every effort is made to reject cobalt to the mill tailings. The tailings can contain as much as 45 pct of the cobalt originally present in the lead ore.
