For ammonium nitrate in 5% mineral oil there were two exothermic regions: the first, a peak (292oC) with a maximum lower than that of neat ammonium nitrate; the second, an apparent doublet (356oC and 387oC). The average total heat of reaction was ~730 cal/g, 26% of the total heat being released in .

The Mineralogy and Production of Lead. The products that accumulate at the bottom are lead, matte (containing iron and copper), speiss (containing iron and arsenic), and slag (containing the silicates, zinc, iron and calcium). Cold air is blown in at the bottom, and flue dust and gases come out the top.
Gold Ore Processing: Project Development and Operations, Second Edition, brings together all the technical aspects relevant to modern gold ore processing, offering a practical perspective that is vital to the successful and responsible development, operation, and closure of any gold ore processing operation. This completely updated edition features coverage of established, newly implemented, and .
Lead sulfate is soluble in water. Lead sulfate is prepared by treating lead oxide, hydroxide or carbonate with sulfuric acid. Alternatively, it can be produced by the interaction of solutions of lead nitrate, lead sulfate is toxic by inhalation, ingestion and skin contact. It is a poison, and repeated exposure may lead to anemia, kidney damage.

The activation of sphalerite by some metal salts has been briefly reviewed and the influence of lead nitrate on sphalerite in the presence of potassium ethyl xanthate has been investigated by a combination of batch flotation tests and solution analyses on pulps containing a mixture of sphalerite and quartz.
Galena or lead sulfide, PbS, theoretically % Pb, is by far the most important lead mineral and the sole primary one.
Beryllium The major ore mineral for beryllium in the is bertrandite while worldwide the major source is from pegmatites that contain beryl. Bismuth Primarily a byproduct of lead processing. Also found in a number of minerals such as bismuthinite and as a constituent in various sulfosalts.
Assuring Water Quality and Safety in Food Processing. In many operations, especially in the seafood industry, water for chilling foods or blending is produced in large icemakers that deposit the ice in bins. Workers often "wade into" ice bins with shovels to fill bins with ice for production use.
Nitrate is used mainly in inorganic fertilizers. It is also used as an oxidizing agent and in the production of explosives, and purified potassium nitrate is used for glass making. Sodium nitrite is used as a food preservative, especially in cured meats.
Lead(II) sulfate is prepared by treating lead oxide, hydroxide or carbonate with warm sulfuric acid, or by treating a soluble lead salt with sulfuric acid. Alternatively, it can be produced by the interaction of solutions of lead nitrate and sodium sulfate.
Recovering the silver. Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zincbearing ores, the Parkes process is used.
Processing technologies for goldtelluride ores. Abstract Gold telluride ores are important gold refractory ores due to the presence of sulfides and other gangue materials. The classification and main physical properties of gold telluride ores were described, and possible treatment methods including flotation, leaching, and oxidation were reviewed.
