Health Risks and Potential Sources of Contamination of Groundwater Used by Public Schools in Vhuronga 1, Limpopo Province, South Africa
Abstract Public schools in most rural areas of South Africa depend on untreated groundwater due to unreliable water supply by the municipalities. This has the potential to cause water-related health problems to school children. Temperature, pH, and electrical conductivity (EC) were measured in situ. Chemical (fluoride, chloride, sulphate, phosphate, nitrate, magnesium, calcium, sodium, and potassium) […]South Africa
Evaluation of high fluoride contaminated fractured rock aquifer in South Africa – Geochemical and chemometric approaches
Highlights • High F (>1.5) is noticed in 51% of locations which are not palatable. • High fluoride is associated with NaCl water types derived from natural processes and evaporation. • PCA and HCA analysis justify that mineral weathering, evaporation and wastewater infiltration regulate the water chemistry. • PHREEQC-Groundwater is undersaturated with Cl and SO4 […]South Africa
Full commercial production from newly opened fluorspar mine Nokeng expected later this month
The R1.7-billion Nokeng fluorspar mine, which unlisted fluorspar developer Sepfluor has built north-east of Pretoria, in Gauteng, was officially opened on Thursday. The mine is one of only two operating fluorspar mines in South Africa, although there is also a fluorspar tailings operation that produces calcium fluoride. The Nokeng operation was expected to ramp up […]South Africa Mining Industry
SK starts work to produce high-purity hydrogen fluoride on its own
SK Group has started to propel its own production of high-purity hydrogen fluoride, which is used for making semiconductors. With SK Hynix, the world’s No. 2 DRAM maker, as its affiliate, SK Group is focusing its capabilities on securing replacement sources across the board. “We are currently working on related development with a goal of […]South Africa Electronics Industry

Reason to switch to fluoride-free toothpaste during pregnancy
The findings of new research may make you want to switch to fluoride-free toothpaste while pregnant. Read on to find out why… A study of over 200 pregnant women and their children found that higher levels of urinary fluoride during pregnancy are associated with more ADHD-like symptoms in school-age children. “Our findings are consistent with […]South Africa
Is the fluoride added to our drinking water unconstitutional?
Did you know that there is fluoride added to our drinking water, even though numerous studies prove it is bad for our health? In September 2001 the Department of Health legislated to add fluoride to South Africa’s drinking water in order to reduce the risk of dental cavities for South Africans who don’t use fluoride […]South Africa
Nokeng mulling two or three more fluorspar mines by 2026 as huge shortage is predicted
Following the breakthrough of opening the first new mine in Gauteng, South Africa, in the last 12 years, which is being developed by producer SepFluor’s wholly owned Nokeng fluorspar mine, the company aims to become vertically integrated in the fluorspar value chain in future. Fluorite ore is mined for the production of calcium fluoride (CaF2), […]South Africa Mining Industry
SepFluor begins building its long-awaited fluorspar mine
SepFluor Limited has begun work on the R1.7bn Nokeng fluorspar mine at Rust de Winter, northeast of Pretoria, with funding provided by private equity and banks. The company, which was unbundled from Sephaku Holdings in 2012, had been planning the mine for at least seven years and originally intended to couple it with a fluorchemical […]South Africa Mining Industry
