Mathematical Modeling and Computational Simulation on Ball Milling in Domestic Goldsilver Mineral Processing Plant

Combined DEM and SPH simulation of ball milling

A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them, and therefore, reduce their consuming power. In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both methods. Then another pilot scale ball mil...

Modeling and Simulation of Mineral Processing Systems

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

The Mathematical Modeling and Computational Simulation for Error-Prone PCR

The successful application of enzymes as industrial biocatalysts requires the availability of suitable enzymes with high activity, specificity and stability in process conditions. However, naturally procreant enzymes are often not optimized to meet these requirements(Zhao et al., 2002). Using the method of directed evolution, we can not only produce useful biocatalyst for the organic chemistry ...

a study on rate making and required reserves determination in reinsurance market: a simulation

reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
