Cominco [Consolidated Mining Smelting Company] A process for absorbing sulfur dioxide from smelting operations. The sulfur dioxide is absorbed in an aqueous solution of ammonium sulfite regeneration is by acidification with sulfuric acid. The ammonium sulfate byproduct is sold. Operated at the Cominco smelter at Trail, Canada, and at other smelters and sulfuric acid plants in the United States. Licensed by the Olin Mathieson Corporation. The name has been applied also to a lead extraction process. 

Suppose EPA scientists are investigating lead contamination of soil near an abandoned mining and smelting operation. How should the soil be sampled so that the analytical results obtained on the individual samples provide a reliable indication of the range and distribution of contamination of the entire site ... 

A critical part of the Kidd Creek mining, milling, and smelting operations is the partnering relationship between Kidd Creek and Durex plus Durex engineering, manufacturing, customer service, and outside material suppliers. All of these people are dedicated to... 

Some very interesting and important phenomena involve small particles and their surfaces. For example, S02 produced from mining and smelting operations that extract metals such as Cu and Pb from heavy metal sulfide ores, can be oxidized to S03 in the atmosphere, thus contributing to acid rain problems. 

High-temperature corrosion and wear is encountered in various industries such as waste incineration, fossil energy, pulp and paper, petroleum refining, chemical and petrochemical, mining and smelting operations. One of the methods to combat corrosion and wear and its control is to select suitable material, i.e., an alloy, for the plant design and maintenance. The selection of proper material for plant design and fabrication is followed... 

Humans are frequently exposed to metals due to their ubiquity, wide use in industries, and persistence in the environment. Many nickel compounds are released into the atmosphere during mining, smelting, and refining operations. Although nickel is poorly absorbed from the gastrointestinal tract, exposure...
