This invention relates to a process for separating suspended solids from the tailings fraction of phosphate ore. Phosphate ore contains substantial amounts of impurities, largely clay and sand. In the usual treatment of the ore, the ore is first broken apart into small pieces and then separated into a concentrate and a waste or tailing.
Sep 01, 2009 The term dry stackable tailings is commonly used in oil sands tailings management to mean a mineral stream left over from the bitumen extraction process which can be stored without the need for dikes or other fluid containment structures. The use of water in the bitumen extraction process results in mineral tailings streams in the form of ...
May 17, 2012 This study appraised the use of phosphate fertilisers in immobilising metals in mine tailings to prevent their uptake into Curly Mitchell grass Astrebla lappacea, when grown on capped, phosphate-amended tailings. Leaching experiments showed that Pb mobility was reduced by both bone meal and superphosphate amendment. Bone meal amendment also reduced Cd mobility.
Tailings characterization The phosphate ore processing resulted in the production of two waste streams to be disposed of at the TSF fines fine waste and tailings coarse waste. The tailings and slime fractions are composed of calcitic to dolomitic crystalline minerals with minor quartz, gypsum and traces of yellow secondary uranium salts also
Nov 05, 2020 01 One. Tailings Wet Discharging VS Tailings Dry Stacking. In terms of tailings discharge methods, there are two main tailings processing methods tailings wet discharging and tailings dry stacking.. Tailings wet discharging is a kind of traditional tailings wet stacking method.
11.21 Phosphate Rock Processing ... and the finer material is disposed of with the tailings. The coarser fraction is ... Mghr 250 tons per hour tonhr of rock will discharge between 31 and 45 dry normal cubic meters per second dry normal m3sec 70,000 and 100,000 dry standard cubic feet per minute
Apr 23, 2020 Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite, calcareous phosphorite, and siliceous phosphorite according to the chemical composition of the
For example, the Raglan decision-making process for the viability of submarine Mine in Quebec is located in an arctic environment and tailings disposal, tools such as an expert system have uses dry stacking to recycle most of its process water and been developed to assist mining project planners explore transports the tailings by truck to the ...
Rock Phosphate Rock phosphate is a rock form of naturally occurring phosphate fertilizer which is formed from sea floor sediments of ancient and current day seas. It is reported as a percentage of phosphorus pentoxide P 2 O 5. Phosphates can be deposited in a

The invention provides a method for separating calcium, magnesium and phosphorus elements from phosphate tailings by adopting water leaching and ammonium leaching. The method comprises the following operating steps calcining the phosphate tailings at a high temperature, circularly leaching by using water, filtering to remove leaching liquid of water insoluble matters, introducing carbon ...
A process for separating suspended clay and sand solids from the slimes of phosphate tailings is described. The suspended solids are rapidly agglomerated and a relatively dense sludge which settles to the bottom of the separation vessel is formed. The sludge may then be discharged into settling ponds for dewatering and compaction.

As the need for dry stack tailings has increased, so has the need for larger and larger dewatering equipment to accommodate the potentially huge volumes of tailings slurry. Some large mining operations process over 100,000 dry tonnes of flotation tailings per day.
In order to explore the variation of the mechanical behavior of tailings in a tailings pond in Hunan Province with the number of dry and wet cycles under different initial water content conditions, the tailings sand samples with moisture content of 6.10, 10.40, 14.00, 18.20, and 21.00 were subjected to 0 to 6 times of moisture absorption ...
Project will generate a high quality phosphate rock product, and that it is economically suitable to be developed based on long term phosphate prices. Construction of the Project is expected to take two years. The Project will operate for 26 years, mining at a rate of 1.75 million tonnes per annum Mta to produce 1.32 Mta of phosphate rock at
The geotechnical characteristics of tailings materials and the stability simulation of tailings pond were studied completely Hu et al. 2016 Coulibaly et al. 2017Du et al. 2019Wang et al. 2018 ...
WaterShed optimizes conditions to allow for rapid drying and tailings consolidation, which accelerates water recovery and results in dry, stable tailings. By rapidly separating process water from tailings for conservation and reuse, WaterShed enables a mine to maintain safer tailings disposal practices, more cost-effective processes, and less ...
Dec 19, 2017 Some sites have progressed even further to dry stacking of filtered tailings. A holistic view to helps identify performance improvements. Thickeners are recognized as one of the more cost-effective technologies for recovering water from tailings streams. Significant energy savings can be achieved by maximizing the recovery of water close to the ...
A typical grinder of 45 Mghr 50 tonhr capacity will discharge about 1.6 to 2.5 dry normal m3sec 3,500 to 5,500 dscfm of air containing 1.14 to 11.4 gdry normal m3 0.5 to 5.0 grdscf of PM. The air discharged is tramp air, which infiltrates the circulating streams.
Apr 01, 2014 For example, typical coal preparation plants discharge 75120 kg of dry tailings per tonne of coal processed. These tailings are in the slurry form, with total solid contents ranging between 20 and 35 ww Ryu et al., 2008, Beier and Sego, 2009, Murphy et al., 2012.
