Heavy mineral sands ore deposits

Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains. It is equally likely that some concentrations of heavy minerals

Heavy Metals Toxicity and the Environment

Heavy metals are defined as metallic elements that have a relatively high density compared to water . With the assumption that heaviness and toxicity are inter related, heavy metals also include metalloids, such as arsenic, that are able to induce toxicity at low level of exposure . In recent years, there has been an increasing ecological and global public health concern associated with environmental contamination by these metals.
