Separation of Dolomite from the South Florida Phosphate
The primary focus of the proposed research is to establish the major parameters and optimize them for separating dolomite from francolite at the bench scale. These studies are to be conducted with natural high dolomitic phosphate rock from loions south of the current mining district in Polk County.

What is Dolomite – Watheroo Dolomitic Lime
Watheroo Dolomitic Lime contains high levels of calcium and good levels of magnesium. It also has some of the lowest sodium levels of any local product currently on the market in Western Australia. It is excavated, then crushed and screened, giving it a greater range of particle sizing than lime sands.
The influences of pH value of solution on the degree and rate of dedolomitization as well as the expansion of reactive dolomitic rock prisms were examined. pH,pH,,pH,

Abstract. A column leaching study was designed to investigate the leaching potential of phosphorus (P) and heavy metals from acidic sandy soils applied with dolomite phosphate rock (DPR) fertilizers containing varying amounts of DPR material and NViro soils.
Preparation of magnesium hydroxide from leachate of
Magnesium in the form of dolomite constitutes a main impurity in sedimentary phosphate ores. Due to depletion of highgrade phosphate ore, the unexploited reserves of phosphate rock tend to contain less phosphate and more dolomitic carbonate (Zheng et al., 2001). The lowgrade ores need beneficiation to be fit for subsequent processing.
