The ARM intensities of the quartz and feldspars range from 3.05 × 10 −5 to 2.70 × 10 −4 Am 2 /kg, and SIRM intensities from 7.45 × 10 −4 to 1.98 × 10 −3 Am 2 /kg (Table 1). Together with the mass fraction of the quartz and feldspars, these values correspond to less than 1.02% of remanence intensity of untreated bulk samples.
yields good results. Quartz in excess of 3 percent remained in only two of the seventeen samples studied. INrnooucrroN Flotation separation of feldspars from quartz was first accomplished in 1936 (Ladoo and Meyers, 1951, p. 216) and has been used commercial-ly for many years.

Separation Method Of Feldspars 52 North. University of minnesotas mineral pages potassium feldspar.Potassium feldspars are the feldspar minerals in which the silicate tetrahedral and aluminum tetrahedra are bound with potassium ions, rather than sodium or calcium ions as in the plagioclase feldspar subgroup.Flotation separation.
THE DETERMINATION OF FELDSPARS IN MUDROCKS USING AN X-RAY POWDER DIFFRACTION METHOD P. M. FELLOWS AND D. A. SPEARS Department of Geology, University of Sheffield, Sheffield, England (Received 6 May 1977) Almtraet--Low albite and maximum microcline were the two feldspars identified in Coal Measures mudrocks. Standard
a plausible method of separating these minerals. In our past studies, amine flotation together with zeta potential, solubility, surface tension, and adsorption measurements were studied in the presence of mono and multivalent salts in order to understand the mechanism of selective separation between Na-and K-feldspars. However,
new condition for separation of orthoclase from quartz by flotation. Washing and high intensity magnetic separation (12 Ampere) afford to reduce the iron-bearing impurities up to 0.09 % Fe^sub 2^O^sub 3^, and the flotation is the best way for the separation of K-feldspar from quartz by appropriate reagents for this purpose (HBr, amine).

For the separation of feldspars from quartz, the traditional methods (gravity, magnetic and electrostatic methods) often fail due to overlap of the densities and magnetic susceptibilities.
separation of quartz from feldspar. purified quartz contains no measurable feldspar, concentrated (40-48%) hydrofluoric acid (HF) is typically used to dissolve the remaining feldspars and at the same time etch the quartz An alternative method for removing heavy minerals and most feldspars is magnetic separation Whilst this is not a new procedure (Rosenblum, 1958), the use of
