In 1906, Dr. Frederick Cottrell, a professor of physical chemistry at Berkeley, successfully precipitated sulphuric acid fumes in a small electrostatic precipitator (ESP) test unit through the use of a high voltage transformer and the newly-invented synchronous mechanical rectifier.
A multi-channel fine dust collector "Buran" (MPU) was installed which reduced the load and wear of the electrostatic precipitator at the second stage of gas purification equipment. In 2017, in order to achieve the maximum possible results of raw materials processing, we built a line for processing slag ferronickel into building materials.

Nickel-cobalt (Ni-Co) laterite deposits are an important source of nickel (Ni). Currently, there is a decline in magmatic Ni-bearing sulfide lode deposit resources (Dalvi and others, 2004). New efforts to develop an alternative source of Ni, particularly with improved metallurgy processes, make the Ni-Co
Mar 24, 2020· Wet electrostatic precipitators are employed in various metallurgical process-es such as zinc roasting plants, nickel flash smelters, lead sinter plants, copper flash smelters, as well as sulfuric acid regen-eration plants. Beltran's advanced WESP design is the most efficient, cost-effective acid mist and submicron particulate collec-tor.
An improved process for roasting nickeliferous laterite ore to convert contained nickel to a leachable form wherein roasting is effected in a multiple hearth type furnace under conditions which are specifically controlled in three basic respects to substantially increase furnace throughput while maintaining a high conversion of contained nickel to a form in which it is extractable by leaching ...
1.2 PARTICULATE SAMPLING FOR ELECTROSTATIC PRECIPITATOR EVALUATION 1.1.2 General Problems Measurements of particle size and concentration are usually made at both the precipitator inlet and outlet to obtain an accurate characterization of the precipitator performance, Gas velocities may vary from 15 m/sec to 30 m/sec, in ducts leading toward or ...
Extraction and separation of cobalt from acidic nickel laterite leach solutions using electrostatic pseudo liquid membrane (ESPLIM) Heckley, Philip Scott ( 2002 ) Approximately 70% of the western world's known nickel reserves are contained in laterite ores, but only 30% of the world's nickel production comes from these ores.
Jul 22, 2021· About 80 to 85% of the incoming laterite ore leaves the reactor as calcined ore, while the flue gases entrain part of the solids as dust. This work presents a theoretical analysis contrasted with experimental results to evaluate the partial reduction of laterite ores in …
Genesis and types of nickel laterites. Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel. This initial nickel content is strongly enriched in the course of lateritization.

Lower pressure drops (0.25 in w.g. vs. 10-15 in. w.g.) and the elimination of broken or blinded bags makes this Wet Electrostatic Precipitator design highly desirable in lieu of fabric collectors. Wider tube spacing also enables the Wet Electrostatic Precipitator to operate continuously or intermittently wet.
How does an electrostatic precipitator work Electrostatic precipitation is an extremely efficient way of filtering fine particles from a flowing gas Electrostatic precipitators ESPs can handle large volumes of air without significantly slowing down the rate of flow because of the low pressure drop across the electrostatic filter.
