Bayesian approach to slope stability assessment by updating probability of failure treated as a random variable
By N. Powell, R. J. Pine
An algorithm is proposed for updating the probability of slope failure on the basis of sequential testing using Bayesian probability theory. The approach is novel and computationally straightforward s

Physical chemistry of 'one-step' copper production from a chalcopyrite concentrate
By J. H. E. Jeffes, C. Diaz
The heat balance and chemical equilibria involved in the production of blister copper from a chalcopyrite concentrate in a single operation are examined. It appears that two stages—one oxidising and o

Kinetics of pyrite decomposition in a fluidized bed: part 1: removal of ambient sulphur vapour is rate-limiting; part 2: influence of transfer processes in the bed
By M. D. Gibbs, T. N. Smith, B. Verbaan
When heated in the absence of oxygen, pyrite from refractory gold concentrates decomposes endothermically to pyrrhotite, releasing sulphur. The decomposition starts at the particle surface and progres
