Cassiterite is a tin oxide mineral with a chemical composition of SnO 2. It is the most important source of tin, and most of the world's supply of tin is obtained by mining cassiterite. Small amounts of primary cassiterite are found in igneous and metamorphic rocks throughout the world. It is also a residual mineral found in soils and sediments.
Grinding is performed using a Rod Mill operating in closed circuit with a Vibrating Screen. This procedure provides a minus 20 mesh product for subsequent table treatment and minimizes overgrinding of the cassiterite. Depending on the characteristics of the ore, the possibility of using a Peripheral Discharge Rod Mill should be studied.
The capacity of the grinding mill varies based on the type of product being ground and the fineness required in the final product. The capacity also depends on the throughput rate, feed size ...
Cassiterite has a significant impact on ore crushing characteristics. Ore hardness is negatively correlated with the product of crushing parameters of A and b, A×b, the effect of crushing energy on crushing fineness is related to crushing parameters A and b, and the influence degree increases with the increase of A.

The chemical state of N was changed in grinding, promoting cassiterite flotation. Abstract In this study, a novel method of promoting cassiterite flotation involves adding PbBHA (Pb (NO3) 2 benzohydroxamic acid) complexes to the cassiterite grinding process was investigated.
Some attempts were made to optimize the grinding size of cassiterite by rod mill, doublesphericity abnormity media, electric pulse fragmentation, thermal pretreatment, and grinding optimization (grinding media, grinding circuits and grinding models) [4,12,13,14]. To a certain extent, these above methods could improve the distribution of ...

There are three pieces of information one should have: 1) liberation size and top grain size of the cassiterite, 2) size by size analysis (SxS), and 3) green field or brown field context. Cassiterite is brittle and the design of the comminution circuit may limit what can be achieved by gravity separation which works best at the coarser sizes.
"When cassiterite polymetallic sulfide ore being grinded in the ball mill, the contradiction between over grinding of cassiterite and under grinding of sulfide ore is inevitable due to their mechanical property differences." Question 2: This is quite confusing.

To attempt a new approach to improve the grinding of cassiteritepolymetallic sulfide ores while simultaneously reducing cassiterite overgrinding and sulfide undergrinding, this article looked into the effects of grinding chemical additives on the distribution of grinding product size.
Grinding plays an important role in mining, construction, metallurgy, chemical, coal and other basic industries. In terms of beneficiation, grinding is the most energy consuming operation. So, reasonable grinding conditions according to the properties of ores is the key to obtain good grinding results and reduce energy consumption and resource waste. In this paper, Tongkeng and Gaofeng ...
Especially our 6S shaking table sales good. Tin / Cassiterite Processing Flow. Usually there are 2 kinds of processing flows of tin / cassiterite. →Jigging → Dehydration. → Jigging → Rod Mill → Jigging → Dehydration. Generally the technological process of gravity separation of placer tin is the first one.
The grinding process is a complex physical, chemical, and physicochemical process, with many factors at play. When the specifications and models of the ball mill are determined, the factors affecting the operation indexes of the grinding process include three facets [1519]: one, the properties of the ore entering the grinding process, including the mechanical properties of the ore, the ...
To solve the problem involved in the grinding of cassiteritepolymetallic sulfide ore in which fine grinding causes the cassiterite to be overground or coarse grinding leads to inadequate liberation of sulfide minerals, the influences of the ball grinding medium on the size distribution of the grinding product were investigated.
Abstract: When cassiterite polymetallic sulfide ore is being ground in the ball mill, the contradiction between over grinding of cassiterite and under grinding of sulfide ore is inevitable due to their mechanical property differences. In this paper, a selective grinding characterization method is pro
1. Introduction. The term chemical additives or grinding aids (GAs) refers to any substance which results in increased grinding efficiency and reduction in power consumption when added to the mill charge (amounts not exceeding wt.% of the feed) during grinding [1], [2], [3].The use of grinding aids to increase mill throughput is quite common in the cement industry [2], [4], [5].
Shi and NapierMunn [39], [41], [42] used the single bobbin Debex viscometer (see Fig. 3) as online measurements of unstable slurries, such as gold, copper and lead/zinc on 16 fullscale industrial grinding mills. A sample of the suspension of interest is taken continuously from process and presented to the bobbin for measurement.
