The flotation results showed that TMNP exhibited strong collecting ability for pyrochlore, but showed no selectivity towards quartz or feldspar. Separation experiments showed sodium aluminium silicate was an effective depressant for the separation of pyrochlore, feldspar, quartz, and calcite.

Protocols have been developed to extract pure quartz from the sediment, e.g., the separation of quartz from feldspar and other heavy minerals can be achieved by applying 2-step density separation. This is followed by HF leaching which usually removes the feldspar contamination from the quartz (if any left). ... Flotation of quartz from …

Quartz is difficult to separate by flotation due to its similar surface physicochemical properties to spodumene. 2 mg/L pectin and 0.005 mol/L NaOL at pH 11 allowed mineral separation. Pectin is chemically adsorbed on spodumene through –COO– and Al sites on spodumene. Pectin pre-sorption interferes with the adsorption of NaOL …
