Dr. Jinrong “Patrick” Zhang is responsible for soliciting and evaluating research proposals and managing projects on phosphate beneficiation and mining. His role involves identifying research and development needs and creating programs to address them.
Patrick Zhang, Research Director - Beneficiation Mining Over 100 million tons of phosphate matrix are transported from mining pits to beneficiation plants in Florida every year. The phosphate matrix is first slurried using high-pressure water guns and then pumped to the beneficiation plants using large-diameter pipelines.
Unfortunately, the Florida phosphate strip mining industry's continuing environmental devastation is not a topic of interest for Florida's local politicians and the local media as well. Little is said publicly about the irreparable damage caused by Florida's phosphate strip mining industry. Get Price

The Mining and Mitigation Program administers reclamation and stormwater management programs for mining operations in Florida, including phosphate. Reclamation standards for phosphate mining are detailed in Part II of Chapter 211 , Part II of Chapter 378, Florida Statutes (F.S.), and Chapter 62C-16, Florida Administrative Code (F.A.C.).
HISTORICALLY, PHOSPHATE MINING OFFICIALS ARE POOR ENVIRONMENTAL STEWARDS. Over the past seventy years, Florida’s phosphate industry let many man-made severe environmental accidents occur one after another over the years, causing serious environmental impacts to pristine “one of a kind” ecological regions of Florida.
Phosphate mining companies own or have mineral rights to over 400,000 acres, mostly in the Peace and Myakka River watersheds, with mining projects planned for over 62,000 acres. Approximately 340,000 acres have already been mined in Florida yet fewer than 70,000 acres have been reclaimed and released.
The Florida Industrial and Phosphate Research Institute, as a member of the Critical Materials Institute, is conducting a systematic study on recovering REEs from phosphate rock mining and processing streams: phosphatic clay, ﬂotation tailings, phosphoric acid, PG, and phosphoric sludge.

To meet the continuing world demand for phosphate, we plan to extend existing mines and develop new mines in Hardee, Manatee and DeSoto counties. By extending existing mining operations onto adjoining properties, we can continue producing phosphate in the area without increasing our water ...

Abstract. The major igneous phosphate deposit in Phalaborwa was discovered in 1904. The establishment of the Phosphate Development Corporation (Foskor) in 1951 catalyzed the development and growth of phosphate mining and phosphate fertilizer manufacturing in South Africa as well as associated businesses.
The stone Valley mining district, also known as the Central Florida district, or the Florida Land-Pebble district, is centered in Polk County, Florida, and extends into Hardee, Hillsborough, and Manatee counties. As of 2013, phosphate was being extracted from five mines in the district, all operated by Mosaic.
1. Introduction. Phosphate rocks of sedimentary origin contain Uranium (238 U), Thorium (232 Th) and its decay products in addition to phosphate minerals (Roesseler, 1990).Considerable variations are found in the stone composition of rock phosphate from different mining areas.
He has 25 years of experience in phosphate research and 6 years of research background in gold mining and cyanide waste treatment. Since 1993, he has served as the Research Director in charge of beneficiation mining with the Florida Industrial and Phosphate Research Institute (FIPR).

Central Florida's groundwater and aquifers are becoming extinct by watershed destruction. via phosphate strip mining operations. Florida's natural watersheds, known to the Florida phosphate mining industry as phosphate overburden, are being destroyed for the beginnings of a phosphate
4. Describe the phosphate cycle, and how the use of stone phosphate fertilizer alters this cycle. 5. Identify how air, water, and land can potentially be polluted by phosphate mining, fertilizer production and fertilizer use. 6. Summarize the effects of phosphate mining on land use in Florida. 7.
As the Florida's phosphate reserves diminish, recovery of the phosphate values from these slimes becomes more and more interesting. Recovery of phosphate from Florida beneficiation slimes 525 Previous Research Recovery of the P205 values from the waste clays is not a novel concept.

Phosphate Rock. The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world.
