Waste Selenium and Tellurium in metallic elemental form including powder

According to the invention, the lignocellulosic material is contacted with the activating agent in fluffed state.

A magnetic elastomer is prepared by mixing a powder-state ferromagnetic material or a highly-permeable material with an elastomer.

The supports are surrounded by coaxial screens with openings in them, said openings corresponding to the outlet areas of the layer material which has been transformed to a dust by the atomising elements.

The treatment can be effected wither in the field or in the packing shed and the active material can be applied to the products as a spray or a dust.

The method is applicable to products in the form of powders having water contents greater than 5 % (m/m), and in the form of pastes ans solutions.

Open flames, arcs and sparks should be avoided in areas where tantalum powder is handled.
