Abstract: Oils are one the most essential ingredients of our daily food. Chemically oils are esters of fatty acids &glycerol. Esters of glycerol are commonly termed as Glycerides. The fatty acids present in oils may be saturated (or) unsaturated.

Basically, oils are extracted from the oil seeds either by mechanical expelling (or) by solvent extraction. The oils, as extracted from the seeds contain many impurities like Free Fatty Acids, Water, Partial Glycerides, Phosphotides, colouring materials (pigments) like β-carotene & Chlorophyll, Free Sugars, Glycolipids, Sterols, Waxes, toxicants like Gossypol & Afflatoxin, residues of pesticides &insecticides like Parathion & Malathion etc. All these impurities must be removed from the oil as they induce undesired properties in the oil & hamper further processes like hydrogenation.

Abstract: The release of heavy metals in to the environment by industrial activities is a serious concern because these heavy metals are extremely toxic and non biodegradable. These will accumulate in living organisms causing various diseases. The potential of metal concentration by certain types of dead biomass has been well established over the last decade. This phenomenon can probably make the most significant impact in using it for removing toxic heavy metals from industrial effluents. An interdisciplinary approach seems essential for bringing the phenomenon to a successful process application stage. In this present article the prediction of process performance and feasibility are discussed.

Abstract: With the help of biotechnology, the race is on to discover the magic bug that will revolutionize the mining industry. The aim of this abstract is to present an eco- friendly technique of extracting the metals, keeping in view the environmental and economical factors. The issue under lime light-BIOLEACHING is the outstanding solution for mining technology. Environmental standards continue to stiffen, particularly regarding toxic wastes, so costs for ensuring environmental protection will continue to rise. The products of biological processes are more amenable to containment and treatment than gaseous waste.

The most important player in the bioleaching process is Acidithiobacillus ferrooxidans. It is a chemoautotrophic acidophile, whose unique ability to oxidise metals, leading to leaching. A consortium of microorganisms namely Acidithiobacillus thiooxidans, Leptospirillum ferrooxidans and thermophilic bacteria are involved in bioleaching. In any event, biomining is now at the top of mining technology, and future development of the technology appears promising.

Abstract: In our day to day activates we come across many types of oils used for cooking, manufacture of paints, soaps etc. These even play a vital role in the production of emulsions. Where as the required properties of oil for particular usage may differ.

In general there are two types of processes involved in oil extraction. They are mechanical & solvent extractions.

In mechanical extraction we get good quality but of less quantity. Where as in solvent extraction we get good quantity but of less quality.

Good quality oils can be used for edible purpose as these have low free fatty acid (FFA) content. Where as less quality oils cannot be used for edible purpose as these have high FFA.

But many industries are using this solvent extraction process. Which mode us to relay on other countries for good quality of edible oils. If we carry out both these processes simultaneously we can get the oil of high quality & quantity in an economical manner.

The present paper deals with the process to be employed the sequence of steps& testing of oils which are produced by the above mentioned method.
