As is characteristic of many other heavily-mined minerals‚ high-grade copper areas are becoming increasingly rare as many of the largest and highest grade areas have been discovered and depleted by mining companies. It was common in the early 1900`s to find sites that had up to 30% copper; however‚ the

Calcium carbonate precipitation Abstract: Introduction: Different minerals precipitation by microbes is a common phenomenon‚ and carbonates are most common mineral formed. Many micro-organisms are having the ability in undergoing the process of mineralization‚ although different minerals have been precipitated by microbes which include carbonates‚ sulphates‚ silicates etc [1]. Amongst all these‚ carbonates are the most common minerals formed. Carbonate precipitation has been applied in several fields
