The discharge of particulate matter emitted dur-ing drying, screening, roasting, smelting, and converting is controlled by using cyclones fol-lowed by wet scrubbers, ESPs, or bag filters. Fab-ric filters may require reduction of gas ...

Sintering - an overview | ScienceDirect Topics

However, a wet scrubber, or electrostatic precipitation, which gives 90–97% particulate control, is now used [17, 34]. Wet scrubber waste water is cleaned by chemical coagulation and settling followed by pH neutralization [ 37 ].

Pyrometallurgy for ceramicists: Chemical aspects

Pyrometallurgy is the treatment of ores or concentrates by thermal methods. Pyrometallurgical processes involve a preliminary step to render the material more amenable to further processing. This ...

The smelting reactions appeared to be essentially complete and the products molten at a distance of about 2 m from the burner, corresponding to a reaction time of 0.1 s. The potential for intense smelting giving high output from relatively small plants was demonstrated and we would expect future application of this technological approach in existing or new smelting vessels. The Inco ...

Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

Pyrometallurgical Processes for the Recovery of Metals ...

The methods are practiced at elevated temperatures to reduce/extract metals, and therefore require high amount of energy input. However, the energy consumption and carbon footprint are lower than in the primary production of these metals, as is the environmental impact due to the elimination of mining waste.

leave the condenser and are scrubbed in a caustic scrubber. This purification process of TiCl4 is quite complex: it involves chemical treatment and a distillation operation. Major reactions [1] [2] [3] At reaction temperatures of around 1000°C the equilibrium shifts towards the CO formation as indicated in Reaction [1]. This CO acts as a reductant in reducing the metal oxides as indicated in ...

The V, K, Na, Cs, S, O catalyst must be molten for Reactions [4] and [5] to occur. It typically melts around 680 K, slightly cooler when it contains cesium ions. Unfortunately, it begins to lose its catalytic power above about 900 K due to the

Scrubber - Wikipedia

Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams.
