Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve a mixture of salicylic acid and CUSO₄ .5H₂O

Mineral processing equipment - gravity concentration‚ classification Depending on the medium forms of exercise and operating purposes‚ gravity separation can be divided into six operations: 1) heavy media beneficiation. Re-election must be conducted in the media‚ with media air‚ water‚ and re-solution or the re-suspension‚ one of the most commonly used are water‚ air‚ called wind beneficiation‚ with density greater than water weight liquid or re-suspension is known as a heavy media beneficiation

Mixture separation Lab I am one of the chemists assigned to design a cost effective procedure for handling the CARBOSE separation and recovery and hazardous waste disposal. The difficulties were trying to figure out is how we can effectively separate Carbose‚ sand‚ and naphthalene? The hypothesis we chose to solve this problem was if we put the mixture into water‚ alcohol‚ and mineral spirts‚ then in each solution one or more substance will not dissolve‚ will be visible‚ and also able to separate
