The worldwide mining industry consumes a vast amount of energy in reduction fragment size from to mineral processing with an extremely low-energy efficiency, particularly ore crushing and grinding. Regarding such situation, this article describes the effects rock fragmentation by blasting on consumption, productivity, minerals’ recovery, operational costs whole chain processing, sustainability ...

Learning representation from relative similarity comparisons, often called ordinal embedding, gains rising attention in recent years. Most of the existing methods are based on semi-definite programming (SDP), which is generally time-consuming and degrades scalability, especially confronting large-scale data. To overcome this challenge, we propose a stochastic algorithm SVRG-SBB, has following f...
