Scheelite Flotation Production Line

Solution Introduction

Scheelite dressing can use gravity magnetic and flotation separation. The types and properties of the ore decide the separation methods and Processes. Basing on good floatability of scheelite the flotation is selected.

Solution Appliion

Scheelite flotation product line is suitable for the scheelite containing multi metals with complex structure.

Solution Introduction

Separation of scheelite and calcspar and fluoriteConcentration pulp with high temperature is common method. Firstthe pulp is concentrated to 60-70 the next sodium silie is added into pulp then the pulp is heated to 80℃ and stirred for 30-60min the last it is diluted with water. The floatation of scheelite is under the room temperature and the product in tank is calcspar and fluorite.

The separation of scheelite and bariteIt is difficult to separate scheelite and barite by sodium silie because of the closed inhibitory action for scheelite and barite. We choose alkyl sulfate as collector to repeatly select barite under the 1.5-3PH and the product in tank is scheelite.

The separation of scheelite and sulfideXanthate is used to capture sulfide minerals in scheelite floatation.We add a little oxide and sodium sulfide to inhibit sulfide without floatation.

The separation of scheelite and Quartz silieOleic acid as collector and sodium silie as inhibitors which could inhibit the quartz and silie gangue and float scheelite.

Solution Case

It interfered the scheelite floatation index for complex composition fine particle size of distribution and containing fluorite and other mineral rich of CaFe. The dressing plant takes the Processing one roughing four cleaning and two scavenging but the final grade of scheelite was not high only 55. So they authorize Xinhai to do technical reconstruction. Xinhai decided to use centrifugal flotation Process after analyzing the properties of ore the detailed index comparison as follow.

After the reconstruction it obviously strengthens the recovery of fine particle and reduces the effect of mud on the separation Process. The recovery index becomes better realizing the comprehensive recycling of resources.
