Degradation kinetics of organic matter in dairy industry wastewater by flotation/ozonation processes
Flotation is a conceptually simple operation; however, as multiphase process with inherent instability, it exhibits complex dynamics. One of the most efficient ways to increase flotation performance by implementing advanced controllers, such Model Predictive Control (MPC). This type controller very dependent on model that represents dynamics process. Although development one crucial parts in MP...
Traditional processing of kaolin is achieved by dispersion of the mined ore and classification by means of multistage hydrocyclones. The inefficiencies inherent to cyclones produce a middling product that is commonly disposed back to the quarry. In this research recovery of kaolinite from tailings of the Zonoupz kaolin washing plant, which is located in Iran, was investigated by cationic flotat...
Agglomeration of coal particles during flotation can be analysed with the Particle Size Grouping (PSG) method. Numerous experiments were carried out to theoretically explain effect carbon agglomeration, but result still remains incomplete. In this paper PSG method was used analyse agglomeration groups initial size 100-400 ?m, maintaining total particle volume. The population definite radius and...
Operational variables of a mineral processing circuit are subjected to different variations. Steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. In thispaper, a dynamic simulator containing some of the major equipment of mineral processing...
Application of gravity and magnetic separation methods to upgrade low grade Manganese ores from Venaj Mine has been reported elsewhere. This paper discusses the results of flotation tests, as well as combination of flotation and magnetic method to concentrate fine particles (less than 150 microns) of manganese ore. Results obtained from various direct and reverse flotation tests, using differen...
Intestinal nematodes are among the most common parasites of dogs, being Toxocara spp. and Ancylostoma spp. threats to public health due to their zoonotic potential. In this study, three parasitological diagnostic techniques for detecting the eggs/oocysts of canine intestinal parasites were evaluated. Fecal samples (n = 285) were collected from the environment (i.e. public streets, squares and h...
Flotation is an important part of coal preparation, and the flotation column is widely applied as efficient flotation equipment. This process is complex and affected by many factors, with the froth depth and reagent dosage being two of the most important and frequently manipulated variables. This paper proposes a new method of switching and optimizing control for the coal flotation process. A h...
This paper reviews recent developments in the fundamental understating of ultrafine (nano) bubbles (NBs) and presents technological advances reagent types used for their generation flotation. The NBs using various approaches including ultrasonication, solvent exchange, temperature change, hydrodynamic cavitation, electrolysis was assessed. Most importantly, restrictions opportunities with respe...
