Flotation machines, and typify all WEMCO machine sizes for 3000 to 1cu. ft. in volume. For any given machine size or rotor diameter, the air transfer pulp circulation relationship can be operationally varied by changing rotor speed and/or rotor submergence in the pulp. Increasing rotor speed at fixed submergence produces higher air transfer and ...

The purpose of making an addition of any reagent to a flotation system is to improve floatability of the desired solid at the desired moment, i.e., to achieve selectivity of separation. Depending on the main aspect of their action, the additives are grouped under different headings. Keywords Sulfide Mineral Sodium Silicate Cyanic Acid Double Salt
Flotation Tank Cells. Table of Contents. The use of tank cells over the years has provided a means for low cost, space efficient, extra capacity in existing flotation circuits. In some cases, new plants have selected tank cells as the machine of choice. Typical tank cells use high efficiency impellers for mixing, which results in low power draw.

Each of the flotation machines contained a certain amount of stagnant volume, and this varied from 7% of the WEMCO machine's effective volume to 45% of the Outokumpu volume. Although the concept of "perfect" mixing is seducing, the best method to interpret the residence time distribution data is to use a multiple-parameter model.

Outokumpu Flotation Machines 2936. A forced air flotation machine typically has stable consistent froth flow over the lip at the top of the machine. This is because the rotor is located at the bottom of the and the tank distance of the rotor to the froth zone minimizes turbulence in the upper region which. Send Message Chat Online
The use of OK-16 flotation machines by Outokumpu Oy is summarized in Table 1. At Keretti, a test run was conducted on a factory scale in the spring of 1972. The results obtained were used in the finalization of the technical details of the OK-16 flotation machines for the Hammaslahti concentration
