11.27 Feldspar Processing 11.27.1 General1 Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium, sodium, and calcium, and it is the most abundant mineral of the igneous rocks. The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O).
Mica minerals can be removed in an amine collector system with a slurry pH of 2.5-3.5; For silicate minerals, when the pH of the pulp is 3-4, a sulfonate collector can be used to separate them to the surface.
The conditions for removing feldspar impurities by flotation are as follows: The sulfide ore is removed by flotation with xanthate collector under the natural pH condition of the pulp; For mica minerals, it can be removed in an …

g/Mg of amine type collector (Custamine 9024, ARRMAZ) at acidic pH 3-3.5 for mica mineral removal, and sink material was received as a mica mineral concentrate (Concentrate 2). The chemical and mineralogical analyses of the samples obtained from the beneficiation processes are presented in Table 2. As seen in Table 2, the Fe 2 O 3
A three-stage flotation process is used to remove mica minerals and feldspar minerals in quartz sand. First-level flotation is to float iron-containing sludge from the slurry using a corresponding chemical system in a neutral or weakly acidic environment;
Feldspars commonly coexist with quartz, mica, and various other minerals. In granite, for example, feldspars are typically associated with quartz and biotite mica .
Reaction-softening by mineralogical changes from feldspars to sericite has been documented from many fault zones. During external crystalline basement deformation in the Alpine orogeny, the Ser Barbier thrust and splay faults in the Pelvoux Massif experienced ultracataclasis and sericitisation. Microstructural information and geochemical data from the fault rocks suggest …

Rubidium typically replaces K in K-feldspar and mica, and can crystallize under a wide range of physicochemical conditions in granitic and pegmatitic systems (Murray and Rogers, 1973, Tischendorf et al., 1997, Černý et al., 2003).Mica and K-feldspar are two of the most important constituent minerals of granites and pegmatites.
3. Magnetic separation. Some mica has weak magnetism and can be removed by magnetic separation, which can remove iron-containing mica.Before considering the magnetic separation operation, the sand and gravel processing system need to conduct a chemical analysis on the properties of the raw sand and gravel and the mica minerals contained in it to …
Most studies concerning the separation of K-feldspar and Na-feldspar have been focusing on the depression of Na-feldspar (e.g. albite) using high concentrations of metal salts (e.g. NaCl) in the cationic flotation of K-feldspar at either acidic or neutral pH (Kovalenko, 1967, Yanis, 1968, Starikova, 1968, Revnivtzev et al., 1968, Marius and Laura, 1970, Demir et al., …
