Grinding, Comminution - Cement and Mining Technology

Grinding, Comminution At CEMTEC's pilot plant, several single machines are in use for conducting tests from batch grinding to continuous grinding tests on a semi-industrial scale. As batch grinds always provide only a partial result or a parameter and do not map the entire continuous process, we also perform continuous grinding tests.

The main objective behind installing these units is to remove gold lock-up within grinding circuits. However, the handling of the high-grade concentrates that are produced has become the no.1 concern for many mining companies. Falcon Concentrators Inc. looked at this in detail and has developed a flowsheet that eliminates the downstream difficulties and security risks by using continuous concentrators within the grinding circuit. The process remains the same within the grinding circuit, but the concentrate treatment is somewhat different yet easy to understand and implement. This report examines the details of installing the Falcon C gravity concentratorswithin grinding circuits and looks at the advantages for such a circuit. See full list on Falcon SB gravity concentrationtechnology has been installed in grinding circuits for 10 years with very successful installations around the globe. The majority of these circuits work very effectively when they are designed as part of a new plant and not as retrofits. Retrofitting often, but not always, is complicated in that the units are installed away from the grinding circuit and the security of the smelt house. This means that the high-grade concentrates, typically 5000 – 8000g/t, produced by the Falcon SB technology either have to be pumped to the smelt house for further upgrading or are collected in a locked container and transported to the smelt house, posing a huge security risk especially in environments which are conducive to theft. Even if the units are designed into a new plant the downstream processing of the high-grade concentrates has to be done. This is normally done on a morning shift when senior people are on the plant to observe the final upgrading before smeltin See full list on Falcon C continuous concentrators have been installed on numerous plants for scavenging of tailings, pre-concentration and for splitting process streams into high-grade and low-grade streams before the leach. The idea behind the circuit described below came from difficulties experienced with security aspects of Falcon SB circuits mentioned above and from clients who do not want high-grade streams in their plants. The Falcon C machine would be installed in a very similar manner to that of the SB units, except that it is not critical to install it close to the milling circuit, yet this would be advantageous. Screening before the concentrator would still be required, but instead of screening at coarser size fractions of 1 or 2mm, screening would have to done at 0.5mm. This is FINE screening but can easily be done, as the tonnage that is fed to the continuous units would be approximately 50% of that of the feed to a batch concentrator. The mass recovery to concentrate on the continuous See full list on A basic comparison is done between a standard batch type installation and the continuous installation. The best way would be to examine the above example of an 80t/h fresh feed grinding circuit. See full list on Conducting Falcon continuous tests and leach investigations to determine if your plant material is amenable to continuous gravity concentration can easily prove the concept. A good rule of thumb would be that if you currently have no gravity in your grinding circuit and your cyclone underflow to overflow ratio is greater than 5 then gravity should most definitely be considered. Now there is an alternative route to eliminating the risks of having high grade concentrates on your plant while still reducing lock-up in the mill. See full list on Before completing any Falcon testwork we recommend that you take two representative samples of cyclone underflow and screen one at 0.5mm and the other at 0.25mm. The undersize of both should be subjected to bottle roll dissolution tests. The dissolution curve should have a residence time to a maximum of five days. The bottle roll tests should be done at standard cyanide and oxygen concentrations. Should either of the dissolution curves generate a residue total gold value of lower than your current plant tailings then there is every reason why the addition of a continuous concentrator in your grinding circuit is a necessity. Should it not give lower results then a regrind is most probably required after the special leach.

Continuous gravity concentration in Gold grinding circuits › 2016 › 09The above mass balance shows a schematic of the proposed installation of a continuous Falcon in the grinding circuit. By recovering 15% of the feed mass on a small Falcon C1000 (30t/h) and treating only 12% of the cyclone underflow, one can easily recover over 80% of the gold by using continuous Falcon gravity units in the grinding circuit.
