The separation techniques from distillation, evaporation, and chromatography are cheap because of the simple tools they use and are fast since they have simple procedures. The recycling process of aluminum is also discussed in the body and the assessment of problems associated with the separation of mixtures. Solid separation has several different methods that are used in the separation of mixed solid substances. The assessment of the different procedures have explained the advantages as being less costly, use of lesser energy and simple while the main disadvantage is the hazardous effect of the materials Introduction The Earth is a unit that is comprised of mixtures of several substances. The modules of separation of mixed material include Solid separation, Solid and liquid separation and Liquid Separation.

The product; slurry, is put into equipment that divides the different density materials by the use of gravity (Ajgaonkar and Dhadke, 1997). The unwanted material falls to the bottom because of the larger weight while the important material is allowed to be collected. Flotation Tanks; The crushed ore is then combined with water and put into a flotation tank which is also a separation process. Air is pumped into the tank and the mixture is disconcerted therefore producing bubbles that the needed minerals stick to(Ajgaonkar and Dhadke, 1997). The bubbles containing the minerals are then collected. Finally, the aluminum is melted down in a heating system at roughly 700 degrees Celsius prior to being pumped into molds and cooled down with cold water until turning solid.

The recycled aluminum can be used for its original form or be used for making an engine block. The period of using aluminum cans and recycling is very fast. The different tools that are used in the separation of the materials are; i. Gravity tractor; it separates the different density materials in the sedimentation process. The cleanliness of metal in its molten state is important for the aluminum industry because a large number of the other metals are valuable than aluminum, and at the moment dirt is introduced into the melt, it is hard to remove it. Therefore the metal casting industry would gain from advanced methods of getting rid of impurities from metal in the molten state. • Another important detail for the steel, aluminum and glass industries is the sorting of scrap materials.

For the aluminum industry, savings on energy can be acquired by melting scrap instead of the actual raw materials. A well-designed scrap sorting can avail better metal purity. Distillation; This is a reliable procedure of separating mixtures that contain two or more substances or liquid form. This is a cleansing procedure where the mechanism of a liquid mixture is heated and then condensed and separated. In simple distillation, a blend is vaporized and the most fickle component at the buck temperature. The steam surpasses through a refrigerated condenser, where it condenses back into its liquid state. The product of this process after condensation is referred to as the distillate. It enables manufacturers to save on the cost of production. • They use less time to separate the mixtures since they require only one cycle to obtain the required product.

Disadvantages of the different procedures of separating mixtures All the processes of separation of mixtures come with operational hazards; it presents a wide range of risks for the staff that is responsible in the industry. One of the rampant hazards is an explosion, which can happen in the case of missing precautions(Hughes, 1982) Summary In this article, the separation of solid substances is explained in depth. The different modules of separating the substances as discussed are explained to be advantageous. Solvent extraction separation of iron (III) and aluminum (III) from other elements with Cyanex 302. Talanta, 44(4), 563-570. Hughes, J. C. High gradient magnetic separation of some soil clays from Nigeria, Brazil, and Colombia. , Degeyndt, E. , Baruh, J. , & Gillard, J.
