Abstract
A procedure for obtaining selenium consisting essentially of preparing a mixture as homogeneous as possible of sulfuric acid and nitric acid that perfectly stirred is reacted with a quantity of cottrell powders or residual powders from the roasting chambers of pyrites continuing the stirring is heated by the assembly formed by such products at a temperature which will advantageously be that of 180 degrees centigrade for two hours; it is allowed to cool by adding to the separated product by filtration it is washed repeatedly with water and the obtained solution is subjected after filtering to a new heating advantageously to 80 degrees centigrade putting it in contact with a stream of sulfurous gas until it is saturated of the same producing consequently, the precipitation of metallic-looking selenium which, after being allowed to stand, is separated from the liquid by means of a final filtration.
