Progress toward a mining strategy based on mineral leaching with secondary recovery

Leaching of Bauxite Residue with Mineral Acids

Aiming at the industrial scale development of a Scandium (Sc)-selective leaching process 14 of Bauxite Residue (BR), a sufficiently numerous set of process design aspects has been 15 investigated, by appropriate exploitation of available experimental data. The interpretation of 16 experimental data for Sc leaching yield, with sulfuric acid as the leaching solvent, has shown 17 significant impac...

Recommendation Strategy based On Relation Rule Mining

Web users are nowadays confronted with the huge variety of available information sources whose content is not targeted at any specific group or layer. Recommendation systems aim at adapting this content to (their guesses about) the needs of a particular user and hence usually compute some sort of relevance score of the manipulated content objects. As direct information about user needs is scarc...

Push recovery with stepping strategy based on time-projection control

In this paper, we present a simple control framework for on-line push recovery with dynamic stepping properties. Due to relatively heavy legs in our robot, we need to take swing dynamics into account and thus use a linear model called 3LP which is composed of three pendulums to simulate swing and torso dynamics. Based on 3LP equations, we formulate discrete LQR controllers and use a particular ...

Neural Transplantation as a Strategy for Recovery of CNS Functions

Transplants of neural tissue have been used for nearly 100 years in order to clarify the mechanisms that underlie development and regeneration of the nervous system. With reports from Sweden and Mexico that autografts of adrenal medulla produce at least transient and perhaps dramatic improve­ment in patients severly disabled by Parkinson's disease, the techniques of neural transplantation have ...
