Mineral Processing Glossary
A ABC Assay Based Controls are changes made to regulatory set-points that are biased on the level or changes in the level of the valuable metal being recovered. Activators Cause a particular mineral to float with a collector when it otherwise would not. Adsorption The gathering of a gas, liquid, or dissolved substance on […]
Locked Cycle Test Procedure – One (1) Product
Here are rough instructions to perform a sequential flotation locked cycle test procedure to assess the overall metallurgy of an ore sample expected to produce only 1 concentrate product. The procedures described in this Method are to be used as a guideline only. The final test conditions and flowsheet are actually determined from in-house experimental investigations. Preparation […]
D12 Agitator Speed for Laboratory Flotation Test
In a lab float test, you adjust to agitator’s RPM based on the volume of the tank you’re working with. Here are suggestions. Rougher Cell: Total cell volume =3.3 liters Slurry volume = 2.5 liters (until this mark slurry filled) –> I use 1000 g test charges Cleaner Cell: Total cell volume =1.75 liters Slurry […]
D12 Laboratory Flotation Machine Parts
I find the parts for a ‘Denver’ D-12 Laboratory Flotation Machine/Cell to be overpriced. From the tank-cell to the agitator blades, Urethane Diffuser Hood, or Impeller and specifically the Tachometer. The primitive D12 Tachometer on a friend’s my D-12 has broken. Refusing to pay $2000 for part of of machine bought used for $10,000 (even […]
Las Luces Copper Mine Project in Chile
Las Luces Grupo Cenizas – Project Mine OP Construction Copper Chile South America. The initiative is property of Minera Las Cenizas S.A. It involves the construction of new works at the Las Luces mine, such as a new waste rock dump, seawater catchment area, slurry deposit and ancillary works. Is also includes another minors works […]
Altın Sallantılı Masası
Altın sallantılı masası temel olarak altın üretiminin son adımında kullanılan düşük kapasiteli bir makinedir. Sallantılı masa beslenen cevheri o cevherin yoğunluk, şekil, öz kütle ve boyuta göre ayıran ince tabakalı ve makaslama akışlı bir proses ekipmanıdır. Mineraller hafiften ağıra ve inceden kalına olmak üzere net ağırlıklarına göre sınıflandırılır. İnce kırılmış yada doğandan alınış cevherler suyla […]
Carlin Type Gold Deposit
Prospectors frequently talk about being in elephant country, meaning in good hunting grounds for big deposits. Historically Carlin Type Gold Deposit are big elephants but until recently they were largely known to occur only in the limited hunting ground of Northern Nevada that limitation is now beginning to change. How Carlin gold deposits fit into […]
Effect of Pre-Aeration and Oxygen on Gold Cyanidation
In your process development you may sometime want to test and see what effect (for your particular ore sample) would the use of oxygenation and pre-aeration have on silver and gold kinetics leach rates and recoveries. Some situations show improved precious metal recoveries, others show an impact of the leach agent’s consumption rate. Here, a […]
Effect of Regrind “Finer Grind” Gold Recovery
Regrinding a flotation concentrate (commonly the rougher or scavenger conc) can often produce gains in final concentrate grades and overall metal recoveries. What is also possible and not unfrequent that all you get is a better concentrate grade. If the valuable metal (in this case Au) is locked with other easy to float sulfides and were […]
