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.
Paste Tailings Plant extends the lifetime of Yara''s tailings storage facility. The paste tailings plant delivered by Outotec as an EPC project to Yara''s phosphate mine, increases tailings solids content, improves tailings beaching properties and extends the capacity and lifetime of the existing tailings .
Processing The Phosphate Risk. Processing the Phosphate, At the processing plant, the slurry mixture goes through a twostep process to separate the phosphate rock from sand and clay particl The first stage is a concentrating process that separates the phosphate pebbles from everything else The average operation can wash and size a maximum of 375 tons of pebbles in .
The Nb beneficiation plant is fed by tailings resulting from the phosphate rock beneficiation process. Figure 2 demonstrates the schematic view of the flowsheet and t he sampling points.

Environmental Protection Agency, Office of Solid Waste, EPA/530R94034, NTIS/PB, November 1994, 135 pages. [Report summarizes EPA site visits to phosphate and molybdenite mines.
Cominco Resources is a private company which is developing the US2billion Hinda phosphate project located in The Republic of the its subsidiary it owns of the Hinda Phosphate Project, which comprises the Hinda Permit (granted in December 2009), and the Kolatchikanou Permit (granted in June 2011). The Hinda project is the world''s largest undeveloped phosphate deposit with .
Jun 01, 2018· 1. Introduction. Phosphate sludge is one of the fine byproducts generated by the phosphate mine activity. It is generally collected during the beneficiation process of phosphate (washing and flotation) (Loutou et al., 2013).This industry generates large quantities of phosphate sludge (Concentrator tailings) that are generally deposited in tailing pounds within the mine site surface, .
During this process, much of the phosphate values are lost to the tailings stream. For example, to obtain 1 ton of rock containing 31% P 2 O 5, about tons of waste containing % P 2 O 5 must be discarded to the tailings impoundment (Figure 1).

Each year around 220 million tons of phosphate rock is processed annually, with China and the US producing a combined 121 million tons. The phosphates extracted are used primarily as a fertilizer in the agricultural sector for commercial farming operations. In this project, we develop and compare flow sheets, capital cost, and

The lack of legislative incentive is likely one of the reasons behind the lack of current larger scale mine tailing recycling. Diminishing primary resources of phosphate and the addition of phosphate rock onto the list of critical materials in EU have already generated a wave of studies on beneficiation of highP content phosphate tailings.
Phosphate mining requires careful management of water and materials as the phosphate is mined, washed, processed, and stockpiled. Water must also be treated and recycled in order to protect the environment. A mine water flow sheet (Figure 3) illustrates the basic flow paths of the process water.
Nov 15, 2015· 1. Introduction. Phosphate tailings are solid wastes produced from mining and beneficiating operations of phosphate rock. About 30–40% of the raw ore is rejected as tailings during a typical phosphate beneficiation operation,, .In current practice, the generated tailings are collected and transported in paste or slurry form and disposed of in large tailings impoundments, which is costly ...
Potash occurs in soft deposits generally associated with sodium chloride and varying amounts of clay slime, which because of its colloidal character, complicates the beneficiation process.. Potash ores generally contain 20 to 40 percent KCL with the balance being NaCl and a small amount of clay slime, the latter usually in the order of 1 to 1½%.
