The stirred leaching tank usually consists of a large tank with a stirring device, such as a stirring paddle or a mechanical stirrer, to ensure uniform mixing of the ore and the solvent. This equipment is widely used in ore processing, and its operating conditions and design vary according to the specific metallurgical process and extraction requirements.
This curve is agitator design specific, but is independent of tank size. Once determined from measurements, e.g., in laboratory small scale tests, this curve can be used to assess sedimentation depth in a large tank for assessing the …
The mixing impeller is a key component of industrial tank agitator design. A tank agitator uses selected mixing impellers rotated in a vessel to create the desired fluid dynamics for the mixing application. This selection is based on process goals and material properties of the mixed fluid.
Chapter 1 discussed parameters that can be leveraged in sample preparation method development. Two of these parameters are agitation conditions and use of particle size reduction techniques. Agitation and particle size reduction can be critical for nonsolution dosage forms, to facilitate dispersion of the sample in order to enhance extraction of the drug.
A HOB filter's output drops water into the surface of the tank and, therefore, creates surface agitation. For canister filters, you need to point the return up towards the surface of the water to agitate it.Lastly, sponge filters can either use an air stone or an airline to operate. The bubbles will rise to the surface and agitate the surface of the water.
Stirred-tank bioreactors Though many types of bioreactors exist, we will focus on stirred-tank bioreactors. The name is accurately descriptive. Cultivation takes place in the bioreactor tank—often called a vessel—and the culture is mixed by stirring (instead of shaking, for example). Stirred-tank bioreactors come in different sizes (for
The stainless steel mixing tank is widely used in such industries of coatings, pharmaceuticals, building materials, chemicals, pigments, resins, food, scientific research, etc. ...

Agitation leaching tanks are widely used in the mining industry for the extraction of gold from ore. This guide aims to provide a comprehensive overview of agitation leaching tanks, including their working principles, design considerations, operational parameters, maintenance requirements, and best practices for efficient gold leaching.
Equipment Design. CSTRs consist of a tank, usually of constant volume, and a stirring system to mix reactants together. Feed and exit pipes are present to introduce reactants and remove products. Pictured below is a CSTR that has had a portion of its side removed to show the interior.
Continuous stirred tank reactor (CSTR) is the most generally employed bioreactor for biohydrogen production in continuous mode because of its simplicity in configuration, easy functioning, efficient uniform stirring, and proper maintenance of temperature and pH (Fig. 10.2A).In these types of bioreactors, biohydrogen generating microbial population is entirely …
The information developed is used to determine the pulp circulation pattern in pachuca tanks of various design. The functions fulfilled by pachuca tanks are discussed, and the considerations affecting a choice of tank described. ... {Air agitation and pachuca tanks}, author={Archie Lamont}, journal={Canadian Journal of Chemical Engineering ...
The second part of our blog series on CFD takes a deeper look at the fundamental principles of computational fluid dynamics and how they apply to tank agitator design. If you need immediate help with your tank agitator design, email applications@proquipinc or call us at 330-468-1850.
This research provides theoretical and technical guidance for the design and production of mineral particle agitators. Keywords Hypergravity, Stirring, Separation, Theoretical, Mineral particle. 1. Introduction Nowadays, mechanical agitation tank is widely used in petroleum industry, chemical industry, ... stirred tank is small, and the ...
A tank agitator is a device used in industrial processes to mix or stir the contents of a tank or vessel. It is commonly used in industries such as chemical processing, pharmaceuticals, ...
The bioreactor design for the BIOX ® process is described elsewhere (Chap. 4). Essential elements of design are presented with a focus on gas dispersion and oxygen transfer including: 42 D. W. Dew et al. † Influence of temperature on bioleach performance and bioreactor design. † Reactor configuration. † Oxygen transfer and agitator ...
The above is an introduction to various aspects of agitation tank for mineral processing. As an auxiliary equipment, the mixing tank is one of the essential equipment in the concentrator. If you want agitation tanks or have other …
• Flow chamber design eliminates internal material build-up • Compact design minimizes interference with plating racks and other in-tank equipment • Wide range of material options • In-tank mounting design eliminates the need for above tank mounting devices • Mounting accessories simplify installation and allow easy,
The Reynolds number is the most widely used number in fluid agitation and most other fluid flow calculations. When gas is introduced into an impeller or is present in the tank, it affects the impeller power draw. Basically, a rotating impeller moves fluid. Agitation results are side effects of how much fluid is moved and how it moves it.

The influence of the agitator's position within the tank on axial velocity was also examined. Laidoudi [5] numerically simulated the flow in a tank stirred by a two-bladed …
Apart from the actual mixer, tank design is the single most important factor in producing a successful result in any process.
Stirred tank reactor (STR) design is critical to the successful performance of a commercial tank bioleaching plant treating mineral sulfides. The reactor duty for a given feed composition and tonnage feedrate is defined by the bioleaching kinetics, oxygen demand, and heat generation, while the gas dispersion and oxygen transfer requirement drive STR design.
We study the mixing structure, mixing performance, and short term dynamics in round bottomed laminar tanks agitated by an eccentrically located angled disc. We define …
Process scale-up is comparably easy, because the stirred-tank bioreactor design is relatively easy to describe with classical engineering approaches (Figure 1) and because it is the bioreactor design for which most research on scale-up phenomena has been conducted. This knowledge has been transferred into single-use technology, as well.
Solids suspension is essential in many different processes. Dynamix provides custom agitation solutions for optimal solids suspension.

Agitation helps maintain consistent temperatures during heating and cooling. It also keeps mixtures from adhering to the equipment or tank walls. Different tank agitation systems can provide varying levels of agitation based on the agitator motor's horsepower and speeds, which provides power for the torque of the agitator.
Mechanical design does not end with the shaft, since strength and practical issues remain for the impeller. Another part of mixer design is the tank in which the mixer is used, since tank dimensions influence mixer features, especially shaft length. Conversely, a mixer requires tank features, such as baffles, support strength, and other tank ...
