PPT-Extracting metals from ores

Grade Objective Outcomes 79 To be able to evaluate alternative biological methods of metal extraction given appropriate information To be able to identify different methods of metal extraction from metal ores. washingtonedu Abstract Extracting knowledge from text has long been a goal of AI Initial approaches were purely logical and brittle More recently the availability of large quantities of text on the Web has led to the develop ment of machine learning This instability is what drives the process of corrosion and it results from the fact that a refined metal is continually trying to revert to its natural state the mineral Some metals do this faster than others The Galvanic Series ranks corrosion te Research Scientist.
