Nonjudicious use of PPIs creates both preventable financial as well as medical concerns. PPIs have been associated with an increased risk of vitamin and mineral deficiencies impacting vitamin B 12, vitamin C, calcium, iron and magnesium metabolism. While these risks are considered to be relatively low in the general …
is the top risk faced by mining leaders, both with regards to the industry as a whole (49%) and their own companies (58%). Of note, large cap companies1 saw economic downturn and uncertainty (44%) and environmental risks, including new regulations (39%) as a greater risk than commodity prices (34%). Despite global volatility, there is a high level

Africa accounts for nearly 30% of the discovered world's mineral reserves, with half of the world's platinum group metals deposits, 36% of gold, and 20% of cobalt being in Southern Africa (SA). The intensification of heavy-metal production in the SA region has exacerbated negative human and environmental health impacts. In recent years, …
Uranium mining and processing are associated with a wide range of potential adverse human health risks. Some of these risks arise out of aspects of uranium mining and processing specific to that enterprise, whereas other risks apply to the mining sector generally and still others are linked more broadly to large-scale industrial or …
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical …
Mining and mineral processing operations often have high water footprints as many stages require the use of water. ... In addition to improving efficiency and cutting costs, this minimises the risk of environmental damage by reducing the toxicity of the tailings. ... Another key environmental problem associated with mining projects is the …
We use this data set to assess the ESG risks associated with the demand for low-carbon energy technologies. ... Mining and mineral processing activities at mine sites usually have high fresh water ...
Without proper precautions, these efforts could come with serious side effects in communities located near critical mineral mines and processing facilities. So it's crucial that governments and companies along the value chain take steps to better measure and manage the water-related risks associated with critical minerals.
Where risks cannot be avoided, supervisors should reduce the time for which the employee uses the machine each day. Instruction and training are critical, and symptoms of back pain in employees should be closely monitored. 4. UV Exposure. For open-pit miners, understanding the risk of over-exposure to UV (ultraviolet) radiation in …
