Go down below, and clean out all that flue dust.

Flue dust sold for incorporation into aggregate rather than landfilled.

Coal can contain significant amounts of cadmium, which ends up mostly in the flue dust.

In 1987, Ivaco was granted a hazardous-waste permit to clean up the flue dust on less than an acre of the property.

New flue dust handling system (wet).

In addition, a totally sealed furnace develops far less flue dust than a semi-closed or an open furnace.

AMI also has an interest in the extraction of metal residues from industrial wastes- predominantly mining flue dust.

A number of elements are recovered in flue gas and flue dust in zinc smelters.

It made nails, and it also generated KO61, or bag house dust, the flue dust emissions classified as hazardous waste.

Development of a dissolution -oxidation- precipitation method for the conversion of As2O3 flue dust to crystalline scorodite)

Maybe it occurs in molybdenite as the sulphide-ReS2and/or Re2S7-commercial source, flue dust from the roasting of Arizona molybdenite. . . .

Zinc residues and pelletised steel plant flue dusts are also incorporated into the sinter feed mix, thus making BZL environmentally friendly, as a consumer of recycled materials.

Based on examination of flue dusts, nickel released from Canadian base metal smelting operations is likely in the form of nickel sulphate, nickel subsulphide, and nickel oxide.

Sometimes the flue dust was wet and clotted with mud, and came up in cakes on the shovel; sometimes it was light, and flew in your nose and eyes.

It is produced in China and Russia from steel smelter slag; other countries produce it either from the flue dust of heavy oil, or as a byproduct of uranium mining.

When the flue dust had been removed from the blast-stoves, I found wheeling and dumping it an easy and congenial set of movements, and consequently took off my loads at a great speed.

The site has been storing a 1,000-ton pile of contaminated flue dust from Bunker Hill Mine and Smelting Complex, an Idaho superfund site, under a tarp since the 1980s.

There are certain advantages of using sinters as opposed to using other materials which include recycling the fines and other waste products, to include flue dust, mill scale, lime dust and sludge.

Cadmium is isolated from the zinc produced from the flue dust by vacuum distillation if the zinc is smelted, or cadmium sulfate is precipitated out of the electrolysis solution.

The plant specialised in smelting low grade ores and other feedstocks, particularly Bolivian tin ore, and the recycling of flue dust, processing materials other facilities or countries were unable or had refused to process.

Therefore, copper, gold and silver are desired; silica is used in the smelting process, sulphur is not wanted; and all other materials, even those that can be managed in the flue dust, should be minimized.

For primary production the feed materials are mainly fume and dust, collected as flue dust in baghouses during the pyrometallurgical processing of zinc, copper and lead and residues resulting from electrolytic zinc production.

This project will develop a pre-commercial pilot recycling facility to extract and recycle ferrite and magnetite pigments from the flue dust, which can be re-sold as cement additives and pigments to the paint and coating industry.

The meeting begins with fly ash; one of the men claims that 4 million tons of coal ash and 2.1 million tons of flue dust was recycled into agricultural fertilizer and sold under names such as Lime Plus.
