Application of horizontal reactor in the treatment of laterite ore by pressurized acid leaching. Our company (Weihai Xintai Chemical Machinery Co., Ltd.) is a manufacturer specializing in the production of magnetic high pressure reactors. The horizontal reactor is an advanced reactor equipment unique to our company. With more than ten years of production experience in the horizontal reactor, rich design concept and extensive customer base. Welcome new and old customers.
First, the advantages of horizontal reactor The horizontal multi-chamber magnetic reactor is a chemical reaction equipment for intermittent operation of multi-chamber reaction. The parts in contact with the reaction medium can be used in various types of stainless steel and titanium, nickel and zirconium. Made of non-ferrous metals, it has good corrosion resistance during the reaction. The kettle adopts a static sealing structure, and a stirrer and a motor are connected by a magnetic stirring system, which has a good sealing effect and a stirring effect. The equipment investment is large, the volume is large, the manufacturing process allows, and the reaction process must be made into a closed type.
It is equipped with a control unit to adjust the working time of the heater according to the set temperature to achieve the purpose of automatic constant temperature. In the same way, according to the needs of the stirring load, the inverter that controls the stirring motor is adjusted to achieve the purpose of speed regulation and stirring.
Widely used in petroleum, chemical, pharmaceutical, pesticide, mining, metallurgy, building materials and other industries, it is an ideal equipment for corrosion resistance, high temperature, high pressure reaction, pressure leaching, slurry heating, extraction process.
The main technical parameters:
Volume: 2000-20000L
Zui high working pressure: -0.1～20Mpa
Zui high working temperature: -18 ~ 300 ° C
Stirring speed: 0-250rpm, frequency control, propulsion stirring is the best way to stir the oil, water bath, steam, molten salt, outer half tube.
Second, the horizontal reaction in the mineral processing industry using pressurized acid leaching treatment of low-magnesium oxide nickel-containing laterite ore, is the use of high temperature and high pressure direct acid leaching laterite ore to extract nickel and cobalt. The process is more advanced, the factory layout is more compact, the floor space is small, the environment in the factory is clean. 3. The process equipment structure and parameters The nickel-bearing laterite ore processed by the plant belongs to the limonite type. If the sulfuric acid solution is used at normal pressure and normal temperature. Leaching, then a large amount of iron present in the ore (the ore containing 68% iron oxide) readily enters a solution containing nickel and cobalt. However, with the same concentration of sulfuric acid solution, leaching at high temperature and high pressure (246 ° C, 3.6 MPa), only a small amount of iron entered the solution and the leaching rate of nickel and cobalt exceeded 95%. The content of alkaline oxidation in the ore is quite low, and it is not necessary to consume a large amount of sulfuric acid to neutralize the alkaline oxide in the ore.
The amount of pressurized leaching sulfuric acid is 22.5% per ton of dry concentrate. The leaching residue contains 51% iron and can be used as a raw material for iron making. The leachate is sent to a precipitation autoclave (118-121 ° C, pressure 1 MPa), and sulfide precipitates such as nickel, cobalt and copper are precipitated by hydrogen sulfide. A sulphide concentrate containing 55% Ni, 5.9% Co, and 1.0% Cu is produced and sent to a refinery for further refining.
