Quantifying texture for acid rock drainage characterisation and prediction by Guseva, Olga

“…When considering texture as a parameter for ARD assessment, the potential for sampling and mineralogical errors arose due to the coarse material size (specifically on the meso-scale) and the limitations on the number of particles that could be assessed. …”

Diagnosis and prognosis of rolling element bearings at low speeds and varying load conditions using higher order statistics and artificial intelligence

“…Empirical models include the fields of regression and classification which are also collectively referred to as supervised learning and is dependent on its construction or optimization on large sets of representative data. In classifying faults in rolling element bearings (REBs) at low speeds and under varying load conditions, support vector machines for regression and genetic algorithm (SVMGA) which is a supervised machine learning algorithm can be used for its classification or regression problems. …”

The development of a mathematical model for the bioextraction of the critical raw material magnesium from mine waste using acidithiobacillus caldus by Raeburn, Yael

“…Using the previously de-termined mineral reactor conditions (0.5% solids loading, τ1 = 14.6 days, pHi = 1), complete extraction of magnesium was achieved at a stock reactor mean residence time (τs) ≥ 10.4 days, establishing an optimal threshold at Vs : 1.4V1. This set-up achieved the same performance as the CSTR with acid in the feed while eliminating the need for synthetic acid. pH control was achieved using a PI controller for the rate of acid addition, for which ITAE tuning parameters were optimised for both disturbance (Kc = 40.7 mol−1.L, τI = 12 h) and set-point changes (Kc = 20 mol−1.L, τI = 326 h). …”

Developing a methodology for reducing diamond breakage within processing plant by Chele, Motsi John

“…Finally, the cone crushers and pan feeders operating philosophy has been improved to start at high speed to achieve choke feed conditions faster and to promote interparticle crushing. The close side settings were also optimized to reduce liner to liner interaction rather enhance particle-to-particle interaction. …”
