At the construction entrance to the Piney Point phosphate plant - off Buckeye Road in northern Manatee County, just south of the Hillsborough County line - the smell of phosphate and gypsum hangs heavy in the air.
Gypsum can also help reduce the amount of phosphorus that leaches from soil to lakes and streams, which can improve water quality and reduce the risk of algal …
Phosphorus (P) is an essential nutrient, often limiting plant growth 8. P fertilisation is therefore needed to sustain productivity in agricultural systems across the world.
The plant was designed to produce 1310 tons daily of phosphoric acid solution of 28% concentration, depending on the type of the phosphate ore produced by the reaction of phosphate with the Industrial Complex produced sulfuric acid, using Paryon Wet Process.
Application of gypsum to soils with high P content, including manure-treated fields, can aid in the control of P export from agricultural fields. Results of this …

Controlled releases at the plant began Tuesday afternoon. The company running the former Piney Point plant, HRK Holdings, says water is leaking out of a pond inside a gypsum stack, which stores wastewater used in the production of phosphate fertilizer. The Department of Environmental Protection approved releasing an unknown …
Calcium carbide slag-phosphorus slag-desulfurization gypsum-metakaolin exhibits excellent synergistic effect. • Desulfurization gypsum promotes the formation of AFt and shortens the setting time of the cementitious system. • Metakaolin promotes the formation of gismondine and improves compressive strength at 7 days and 28 days.
The soil from the solid waste disposal area i.e. gypsum pond and the soil from the rock silo which is the phosphate rock storage area showed higher levels of natural radionuclides than other locations in the plant premises.
In order to solve the problems of low phosphorus removal efficiency and high operating cost in wastewaters, this study took flue gas desulphurization (FGD) gypsum, a by-product of coal-fired power plants, as a low-cost calcium source, and combined with traditional phosphorus removal agents to achieve high phosphorus removal efficiency …
Nitrogen, phosphorus, and potassium are the three macronutrients that plants normally obtain from the soil, and all three are essential for plant growth.
11.16 Gypsum Manufacturing 11.16.1 Process Description1-2 Gypsum is calcium sulfate dihydrate (CaSO4 2H2O), a white or gray naturally occurring mineral. Raw gypsum ore is processed into a variety of products such as a portland cement additive,
Phosphate rock contains the mineral phosphorus, an ingredient used in some fertilizers to help plants grow strong roots. Phosphate rock contains small amounts of naturally-occurring radionuclides, mostly uranium and radium.
Phosphogypsum is an industrial byproduct from the wet preparation of phosphoric acid. Phosphorus building gypsum can be obtained from phosphogypsum after high-thermal dehydration. This study aimed to analyze the influence of ball milling with different parameters on the strength of phosphorus building gypsum. In this paper, the …
Phosphogypsum (also referred to as PG) is gypsum which is created during the production of phosphorus fertilizer. This by-product is increasingly being used around the world in areas like agriculture, road-building, and infrastructure. Dr. Julian Hilton, Chairman, Aleff Group, UK Dr. Connie Nichol, Environmental Soil Scientist, Nutrien, …
Phosphate processing plants in the greater Tampa Bay region have caused some of Florida's worst environmental disasters. Accidents like the spill at the former Piney Point plant fill the history books in Florida. ... Donica is the court-appointed receiver in charge of closing the old phosphate gypsum stacks, which suffered a tear in 2021 that ...
Use a soil analysis no older than 1 year that provides cation exchange capacity (CEC), calcium, magnesium, pH, and phosphorus, as a minimum, to plan the appropriate application rate of the gypsum products.
The gypsum improves soil infiltration and curbs algae growth by binding with phosphorus in the soil, so that less phosphorus is available to algae as a nutrient. The studies have been instrumental in setting key …
This study delves into the multifaceted effects of multi-walled carbon nanotubes (MWCNT) incorporation on phosphogypsum's properties. We investigated …
The gypsum improves soil infiltration and curbs algae growth by binding with phosphorus in the soil, so that less phosphorus is available to algae as a nutrient. The studies have been instrumental in setting key policies.
Phosphogypsum (PG) is a solid waste product generated during wet-process phosphoric acid production. Various impurities considerably reduce the purity, …
Purpose The present study aimed to assess the synergistic effects of superabsorbent polyacrylamide hydrogel (SPH) and gypsum on colloidal phosphorus (CP) release from different farmlands (i.e. tea, vegetable, and paddy soils). Materials and methods A laboratory experiment was carried out to examine the effects of SPH at …
Due to the higher 30-min slump loss and the lower 1-day strength of phosphorus building gypsum (PBG), its use for gypsum-based self-leveling mortar is…
