US4488959A Scheelite flotation process Google
A process for separating scheelite from gange wherein the ore is ground with 0.4 to 10 grams of alkali metal carbonate per kg. of ore, forming a pulp and removing sulfide minerals from pulp liquor. Carrying out froth floatation in the presence of paraffin oil, 0.1-0.4 gram of fatty acid per kg. of ore and 3.2-5.5 grams of sodium silicate per kg. of ore wherein the weight ratio of paraffin oil
Scheelite Flotation From Tarouca Mine Ores: Mineral
2019-4-15 · The production of high-grade scheelite concentrates from low-grade ores involves a set of operations to eliminate the undesirable minerals. The present work includes as main goals the study of the effect of (i) meteorization of the ore, (ii) pH during the grinding, (iii) the amount of soda ash in grinding process, (iv) the depression or previous flotation of sulphides, (v) and the
Froth flotation of scheelite A review ScienceDirect
2018-5-1 · The lime flotation process has shown that separating scheelite from siliceous gangues is relatively easy. However, a calcareous gangue brings about major changes, as many calcium-bearing minerals exhibit similar surface properties to scheelite (solubility, surface species, zeta potential) as well as similar responses to collectors ( Fig. 6
PHD THESIS ON SCHEELITE FLOTATION Nathalie
The focus of the thesis is to understand the mechanism of two important depressants in scheelite flotation, sodium carbonate and acidified water glass (AWG), and linking said mechanism to process
Scheelite flotation Amax Inc.
A scheelite concentrate is recovered from a scheelite ore containing silicate minerals and other calcareous minerals by froth flotation which process comprises grinding the ore sufficiently fine to liberate the scheelite grains, pulping the gound ore with water to form a slurry containing between about 20% and about 40% solids by weight, sequentially conditioning the slurry with at least one
Laboratory Testing of Scheelite Flotation from Raw Ore in
2020-10-31 · Cleaner flotation is a process to float scheelite only for producing a high grade concentrate as possible without the addition of any reagent. Furthermore, a locked cycle test was carried out based on these results to calculate material balance to provide a
Laboratory Testing of Scheelite Flotation from Raw
A fatty acid collector is extensively used in scheelite flotation from the raw ore during the process of separation [2,8,13,15,21].Scheelite is often associated with other Ca-bearing salt-type minerals such as calcite and fluorite, which has similar characteristics [5,6,7,22,23].Their dissolved mineral species in the pulp might be some reactions such as hydrolysis, precipitation and adsorption
