Improvement of sylvite flotation from halite by starvation

It has been demonstrated that starvation feeding the collector is an efficient method for obtaining high grade sylvite, because it can not only improve the separation of sylvite and halite but also decrease the consumption of Over 80% of the world’s potash fertilizer is produced by the selective froth flotation of KCl (sylvite) from NaCl (halite). However, all the surfactants used in the potash froth flotation process are traditional monomeric surfactants contain a single similar hydrophobic group in the molecule, which leads to a low production efficiency.Flotation of sylvite from potash ore by using the Gemini surfactant

Improvement of sylvite flotation from halite by starvation feeding

As a flow that can obtain a high grade product, due to its high selectivity with a decrease in dosage, a starvation fed reagent is often applied to separate particles with similar floatability. 9 In this study, we paid more attention to the flotation process, and attempted to improve the separation of sylvite and halite with a strategy of starvation The paper is about the froth flotation process and its application. It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores. Froth(PDF) Froth flotation process and its application

Process Design and Economic Evaluation for the Recovery of Halite

For the solar salt process (Table 5), the simulation predicts 54,650.53-kg crystalline halite with 99.58% halite content that is produced from 500,000 L (545,289.16 kg) of brine per batch. It further predicts production of 11,656.76 kg and 13,209.32 kg of soda ash and thernadite respectively.In froth flotation separation process, the collector molecular design has a crucial effect on potash processing to ensure sustainable production of potassium fertilizer (KCl) that is important to secure food supply in human society.

Intensification of the flotation separation of potash ore using

The two main components of sylvinite ores, sylvite (KCl) and halite (NaCl), are water soluble minerals; hence, the flotation process with cationic surfactants is performed in a saturated brine of NaCl-KCl salts with a concentration exceeding 6–7 mol /L (Laskowski and Castro, 2015), which is ten times higher than the concentration in sea product by a combination process of cold decomposition and otation.3,4 With regard to the otation process, the main purpose is to separate sylvite from halite and obtain high grade sylvite. However, in the production process of SLNP, there is a serious problem that the Na+ grade (7–9%) in sylvite concen-Improvement of sylvite flotation from halite by starvation feeding

Improvement of sylvite flotation from halite by starvation feeding

The reason for the upward floating of halite explored by SEM-EDS was that sylvite was locked with halite, thus it can float up along with sylvite. According to the analysis results, a strategy of starvation feeding the collector was employed to increase the flotation rate difference between sylvite and halite, and consequently improve the The flotation-based separation of the salt minerals sylvite (KCl), halite (NaCl), carnallite (KClMgCl 2 6H 2 O) in saturated solutions of electrolytes (KCl–NaCl–H 2 O and MgCl 2 –KCl–NaCl–H 2 O is discussed.
