Activation mechanism of lead ions in cassiterite flotation

The floatability of cassiterite treated with lead ions was lower than that of the untreated cassiterite when the SHA concentration was less than 1 × 10 −4 mol/L. These two combining effects, i.e. increasing the hydrophobicity of cassiterite particles and reducing the single bubble size, are beneficial to the flotation A recipe of surfactant for the flotation of fine cassiterite particles

OIL ASSISTED COLUMN FLOTATION OF A CASSITERITE-BEARING

The tests are performed using an oil-assisted column flotation approach to process very fine ore fractions and avoid losses of cassiterite into the tailings.The main useful minerals of cassiterite polymetallic sulfide ore were marmatite, cassiterite, pyrite, pyrrhotite, jamesonite, arsenopyrite, and marcasite. The main gangue minerals were quartz and calcite. All samples were broken into −1.7 mm particles after cleaning, drying, crushing, mixing and reduction processes.Grinding Optimization of Cassiterite-Polymetallic Sulfide Ore

The open-circuit flotation concentrate has a Sn grade and recovery of 12.01% and 40.59%, respectively, indicating the excellent flotation separation of cassiterite from its associated gangue minerals.Desliming is the key part of the tin gravity separation process, which directly affects the separating effect. In China, more than 80% of the raw tin ore is placer tin deposit. The desliming process is actually divided into two stages, one is dissociation and dispersion of the slime, and the other is the separation of mud and sand.Tin Processing Equipment, Process Flow, Cases JXSC Machine

Study on the Grinding Law of Ball Media for Cassiterite MDPI

To solve the problem involved in the grinding of cassiterite–polymetallic sulfide ore in which fine grinding causes the cassiterite to be overground or coarse grinding leads to inadequate liberation of sulfide minerals, the influences of the ball grinding medium on the size distribution of the grinding product were investigated. Two types of ball filling Sodium oleate (NaOL) and benzohydroxamic acid (BHA) are commonly used scheelite and cassiterite flotation collectors. Hydrophobic flocculation flotation of fine minerals has been extensively studied and reported under a NaOL system, but not under a BHA system.

Tin values in the form of cassiterite (SnO 2 ) are recovered from aqueous pulps of finely divided cassiterite-bearing ore, preconcentrate or concentrate by froth flotation. The ore pulps are deslimed thoroughly, partially or not at all. Slimes, gangue or waste minerals in the pulps are selectively depressed by use of a metal salt/silicate reagent combination.
