The feed material was ground to 90% passing 74 μm and subjected to a low-intensity magnetic separator (~0.2 T) to remove the magnetic gangue minerals. The nonmagnetic fraction was further subjected to a high-intensity magnetic separator (1.4 …
The paper is about the froth flotation process and its application. It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores.
Picromerite and halite were ground by hand and sieved to obtain particles in the size fraction of 44 – 250 μm. For single mineral flotation tests, 15 g of picromerite or halite samples and 45 g of mother liquid 2 were introduced into a 40 mL flotation cell, stirred for 3 min, and then the pulp pH was adjusted to the desired value.

1. Introduction. SDIC Xinjiang Lop Nur potash Co. Ltd. (SLNP) is the biggest K 2 SO 4 production company in the world with a K 2 SO 4 yield of 1.6 million ton per year. 1 The K 2 SO 4 of SLNP is obtained by the conversion of sylvite (KCl) and ite (K 2 SO 4 ·MgSO 4 ·6H 2 O) with the addition of water, 2 among which sylvite is gained from a …
Reverse flotation of coal can be explained as a process where valuable minerals are depressed, while undesired and unhealthy minerals are floated with the help of some reagents. Nowadays, conventional enrichment method of coal could not achieve removing unhealthy minerals partially from internal structure of coal such as sulfur, Hg, …
where r is the measured cumulative recovery of either valuable or gangue at time t, R is the calculated equilibrium recovery as t → ∞, and K is a first-order rate constant of mass removal (units of time −1) that describes the shape of the time–recovery curve at small flotation times.Thus, each time-recovery profile can be characterized by two parameters, …
The two main components of sylvinite ores, sylvite (KCl) and halite (NaCl), are water soluble minerals; hence, the flotation process with cationic surfactants is performed in a saturated brine of NaCl-KCl salts with a concentration exceeding 6–7 mol /L (Laskowski and Castro, 2015), which is ten times higher than the concentration in sea …
This process has been used in the paper industry to recover the process water. Because of the expensive equipment required to maintain the vacuum, the flotation process has been replaced by pressurized flotation. ... In the case of halite, NaCl, flotation is not achieved with amines under any circumstances. On the other hand, good recovery is ...
Sinking is just the opposite process of floatation which means the tendency of an object to go deep down to the lower levels of the fluid. The phenomenon of floatation totally depends on the density of the object …
