Its chemical structure was characterized, and the flotation effect of wolframite and calcite was studied. (1) According to the micro-flotation test, when the optimum pH of wolframite flotation was 7, and the dosage of AATS was 1×10 −4 mol/L, the wolframite recovery was 93%, and the of calcite was about 10% merely. When the …
The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants.
The results show that such data integrations enable on-stream and quantitative identification of slurry mineral contents, especially for scheelite, wolframite, …
A rod mill is a type of ore grinding equipment used to grind materials into fine powder. Unlike ball mills, rod mills use long steel rods instead of balls as the grinding medium. Rod mills are ideal for breaking down materials such as minerals and ores. In this article, we'll provide a comprehensive guide on what a rod mill is, how it works ...
In this post, we're going to learn more about rod mill. We'll cover it from two aspects: 1. Working principle. 2. Structure. Let's dive right in! 1. Working Principle of Rod Mill. Rod mill is a common equipment for grinding operation in mineral concentrator, which is mainly suitable for rough grinding operation.

3.2.1.1. Inorganic depressant. Water glass is the most commonly used depressant in scheelite flotation. The water glass is represented by Na 2 O·mSiO 2, where m is the modulus and the acidity/alkalinity of the water glass are usually divided by m = 3; when m < 3, the depressant is alkaline and is neutral when m ≥ 3.
Abstract. Owing to the depletion of wolframite, the focus of tungsten extraction has gradually shifted to scheelite. However, separating the associated …
A complete cassiterite processing line is washing — crushing — gravity separation — grinding — flotation separation — magnetic separation. 1. Washing cassiterite. First, wash the ...
Process: √ In coarse grinding stage, Xinhai adds xanthophyll collector to float various sulfides first; √ In the gravity separation stage, Xinhai adopts the shaking table to get some or all qualified tungsten concentrate. √ For …
The coarse concentrate is ground in a rod mill and sieved with a vibrating screen. Ore crushing and grinding tests show that the 6-mesh screen can effectively concentrate about 50% weight of the feed containing appreciable amounts of free cassiterite, and minimize over-grinding.

In this study, the surface properties and flotation behavior of scheelite particles with a size of − 74 + 38 μm produced by ball and rod mills were studied …
ABSTRACT Flotation separation of scheelite from calcite is difficult because of the existence of the same cation in the minerals and similar physicochemical characteristics. Many studies have been performed to determine the selective depressants for calcite, but the separation of scheelite from calcite is still a big problem. In this …
The rod mill is generally wet overflow type used in the first stage grinding, especially in artificial sand and stone, mineral processing plant and power sector of chemical plant. Product Principle The rod mill is driven by motor with speed reducer and peripheral large gear, or low speed synchronous motor with peripheral large gear.
Scheelite (CaWO 4) and wolframite ((Fe, Mn)WO 4) are the only tungsten minerals mined commercially and are mainly found in five types of deposits: skarn, vein/stockwork, porphyry, disseminated and stratabound.Gravity concentration and flotation are the beneficiation techniques most commonly applied to scheelite ore, and …
Process: √ In coarse grinding stage, Xinhai adds xanthophyll collector to float various sulfides first; √ In the gravity separation stage, Xinhai adopts the shaking table to get some or all qualified tungsten concentrate. √ For the tailings after the gravity separation stage, Xinhai floats the scheelite with oleic acid collector, and get ...
Scheelite (CaWO4) and Wolframite ( (Fe,Mn)WO4) are the principal minerals of tungsten, but other important minerals include ferberite (FeWO4) and huebnerite …
Micro-flotation experiments were conducted to study the flotation behavior of the ball and rod mill particles in the fraction of − 74 + 38 μm. The flotation results, using different concentrations of NaOL solution at a pH of 6.3–6.5, are provided in Fig. 3. Both the ball and rod mill particles have a similar trend of flotation recovery.
