Florida Phosphate Mining Waste By-Products Are Hazardous

2016-1-4  During the process of making fertilizer the Florida phosphate mining industry also produces toxic waste by-products. The by-products include concentrated airborne radiological agents. The DEP says these agents are toxic to all living things. During the production of fertilizer from phosphates, many unwanted toxins or waste by-products are made ...

Mining Processing Byproducts - Housin

Byproducts The Phosphate Risk. Another byproduct of phosphate strip-mining is waste clay. The clay is filtered from the slurry mixture during processing. This waste clay contains toxic levels of uranium and radium and cannot be put back into the environment. Instead, the clay is stored in huge settling ponds on the mine

EPA Revokes Use Of Phosphate Waste Products In Road

2021-7-3  The Biden administration has withdrawn a previous approval of the use of phosphogypsum - the toxic byproduct of phosphate mining - in road beds. This means the mountains of phosphate waste peppering Florida's landscape will remain. The decision overturns a Trump-era move by the U.S. Environmental Protection Agency to allow use of the byproducts ...

Elaboration of geopolymers based on clays by-products

2020-7-10  During the open-pit mining, the intercalation layers are blasted and removed as waste rocks usually deposited on large surfaces called “stockpiles” within the mine site. The phosphate waste rocks are chemically stable and don’t present any risk of mine drainage contamination (Hakkou et al., 2016). However, they could cause arable lands ...
