Froth Slurry Pump
In mining applications, froth flotation is often used during the mineral processing stages to help separate the solids from the heavy slurries by taking advantages of differences in their hydrophobicity. The first step in the process is to gather and finely crush and grind chunks of ore into fine particles, with the goal of separating the individual minerals into their own separate grains. The particles are then mixed with water, and the entire solution is then pumped using a slurry pump to the mineral processing facility in slurry form and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical. This allows the minerals to bind to the air bubbles of the froth, bringing the majority of valuable minerals to the surface of the slurry in a concentrated form, making it easier to collect. Frothing agents, or frothers, can also be added to the slurry mixture to promote the formation of a stable froth on the surface of the liquid.
In this sense, mining froth can be described as an aerated slurry that either occurs naturally or, in some cases, purposely created to assist with the separation of minerals. Froth flotation is an important step used for the recovery and upgrading of sulfide ores, allowing far more economic recovery of valuable metals from much lower grade ore. Frothing is usually performed in multiple stages to maximize the recovery of target minerals. Historically first developed and used in mining, this process is now also used in other industries including paper and pulp pump applications and wastewater treatment applications.
Feature and Application
Naipu® NAF Series Froth Pumps are the latest generation of froth pump based on advanced technology at home and abroad.It is designed to pump frothy slurries more efficiently by de-aerating or partially de-aerating the froth ,by an induced vortex principal,before it enters the pump head.
It is double casing vertical pump complete with hopper.It features a wide choice of replaceable abrasion resistant metal or moulded rubber casing liners and impellers.The hopper-tank is fabricated with steel plate. Its inner wall of the tank can be covered with liner according to different medium pumped.
Important design features of Naipu® NAF pumps include:
- Excellent performance, easy assembly & disassembly, high reliability etc
- Don't need shaft seal and sealing water.
- It can be driven by direct connection or belt , and the belt & pulley can be altered easily for changing the pump speed according to working conditions.
- The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
