Separation of dark-colored minerals from feldspar by

2004-1-26  Several conventional enrichment techniques, such as hand sorting, magnetic separation and flotation, are employed to remove coloring impurities including iron-bearing minerals from feldspar,, . These techniques are not very effective for the treatment of ultra-fine particles (slimes), less than 20 μm, which will be generated as a result of comminution to liberate minerals.

Developing Effective Separation of Feldspar and Quartz

In order to improve the purity or the whiteness of feldspar, flotation [3,4,5] and magnetic separation are typically used to remove associated minerals (such as quartz, and dark-colored minerals rich in iron) from feldspar [6,7,8]. Traditionally, there are two main flotation separation processes to remove quartz from feldspar.

(PDF) Separation of dark-colored minerals from feldspar by

Feldspar ores usually contain some amounts of impurity dark-colored minerals (DCM), rich in iron. Such ores must be comminuted for the liberation and separation of the said impurities.

Using pure albite and quartz minerals, the separation of albite from quartz using mixed cationic/anionic reagent schemes is assessed through Hallimond flotation, zeta

Developing Effective Separation of Feldspar and Quartz

Consequently, the negative surface charge of feldspar increased at pH 2, which allowed for the flotation separation of the feasible minerals. This took place via an increased electrostatic adsorption between DDA and Na, K, Al on the feldspar surface, which effectively increased its hydrophobicity and as a result, improved the floatability of feldspar.

SELECTIVE SEPARATION OF Na- AND K-FELDSPAR FROM

2016-4-1  Literature results discussed earlier for the selective separation of sodium feldspar from potassium feldspar seems to employ only HF medium. The first mechanism on fluoride activation of feldspar at low pH has been given by Buckenham and Rogers. They proposed that fluoride gives rise to sites of charged aluminum/fluoride complexes at the mineral surface on which cationic collectors adsorbs. Second explanation was given by Smith who investigated the activation of beryl and feldspar with fluoride in cationic collector systems; He proposed that fluoride

Heavy Mineral Analysis Technique Heavy mineral separation

Separation. Using a heavy liquid with a specific density of 2.8g/ml, the “heavy” grains are separated from the “lighter” grains which mostly consist of quartz and feldspar. The separation is done in a separating funnel in a temperature controlled room of 20°C. The “heavy” grains will accumulate in the bottom of the funnel above the
