Analysis of the Effect of Magnetic Separation
Processing Parameters for the Treatment
of Mining Waste
The reprocessing of mining waste remains a challenge to achieve ecological sustainability. Magnetic separation is one of the most effective methods for physical separation of materials. In this research, a magnetic separator with permanent neodymium (Nd-Fe-B) magnets is developed to remove magnetic particles contained in mining waste powder. Experiments with different variables were carried out to determine the design parameters for the process, such as: the separation between magnets, the flow of the material and the concentration of solids in the slurry. In this investigation, a Taguchi L16 4k matrix was used, considering that the process has 3 controllable factors with 4 levels each, for which 64 samples were prepared to obtain the parameters that give us a process that works with greater consistency, considering 2 noise factors (% of magnetics in the sample and the accumulation of particles). The results of this research will be the basis for the manufacture of a magnetic separator for the treatment of mining waste.
期刊介绍：
One of the most important challenges facing the contemporary scientific world are problems connected with environmental protection. Intensive development of industry and agriculture has led to a rise in living standards on one hand, but an increase in environmental degradation on the other. This degradation poses a direct threat to human health and life. Solving these ever-increasing problems which seriously endanger our civilization require the united efforts of scientists and field researchers of many branches.
The "Polish Journal of Environmental Studies" publishes original papers and critical reviews on the following subjects:
-Basic and applied environmental pollution research, including environmental engineering
-Pollution control of atmospheric, water (marine and fresh), soil and biological materials
-Determination of harmful substances, including their metabolic breakdown patterns
-Analytical methods for metabolic breakdown patterns or other chemical degradation patterns in the environment and in biological samples
-Development of new analytical methods, instruments and techniques for controlling pollutants
-Circulation of pollutants in the environment and their effect on living organisms
-Environmentally oriented catalysis
-Hazards to human health and safety
-Waste utilization and management
-Land reclamation
-Conference reports, scientific and technical reports and book reviews
