A process is described for separation of oxidic minerals, such as phosphate. The process is a froth flotation process utilizing a novel collector, which is comprised of: 1. tall oil or any other commercial fatty acids that may contain rosin; 2. fuel oil; 3. N-substituted-N-mixed alkyoxy-propylmaleimic acid derivative; 4. fatty acid sulfonate; 5. alkyl alcohol ether sulfate; 6. alkyl alcohol
Preferably, this slurry has a solids content of from 10% to 20% by weight and a particle size of less than 500 microns. The aqueous slurry can be formed by adding water to phosphate rock or phosphate slimes. For effective beneficiation of phosphate rock, a surface conditioner must be added to the slurry prior to agglomeration
Get PriceIt is therefore an objective of this invention to provide an improved process for the beneficiation of central Florida phosphate rock. It is another object of this invention to provide an improved reagent and pH range for the conditioning of flotation feed slurry prior to rougher flotation of phosphate rock
Get PriceJan 08, 2016 The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of important parts of manufacturing process
Get Pricerock phosphate can become soluble (and available to plants) either by chemical ... At the beneficiation plant, the slurry is first run ... grains. Finally, a process called flotation is used to separate the phosphate from smaller-grained sand. In this process, the phosphate is coated with a hydrocarbon. When bubbles move through the liquid, the

Get PriceOct 04, 2019 The physical and chemical characteristics of mined phosphate rock will vary temporally as the location and nature of the ore body changes and as the type of equipment used in the beneficiation processes change over time. For the Dorowa phosphate rock (DPR) in Zimbabwe where economic challenges have affected the viability of phosphate rock mining and led to the closure of
Get PricePhosphate rock needs processing to reduce the content of gangue minerals such as silicates, carbonates, and clays to meet the requirements of the phosphate industry. ... Beneficiation of Florida
Get PriceThe enrichment of the low-grade-phosphate ore of the Tozeur-Nefta deposit was investigated using scrubbing-attrition, ball grinding and anionic/cationic reverse flotation in order to separate phosphate-rich particles from their gangue. The choice of the beneficiation process was based on the petrographic, mineralogical and chemical analyses. The petrographic and mineralogical studies have

Get PricePhosphate rock from the mines is first sent to beneficiation units to separate sand and clay and to remove impurities. Steps used in beneficiation depend on the type of rock. A typical beneficiation unit for separating phosphate rock mined in Florida begins with wet screening to separate pebble rock
Get PriceThe beneficiation process could include a large variety of operations depending on the rock impurities content, the particles size and their hardness. The main operations are: classification, electrostatic separation, magnetic separation, crushing, grinding, dry enrichment, cyclonning and calcination and wet processes like chemical leaching, washing, hydrocyclonning and flotation. The main beneficiation
