At the beginning of the XXI century the anthropogenic uncontrollable industrial activity continuously disturbs the equilibrium of the planet formed for millions of years. A number of metals of vital importance decrease calamitously or disappear completely. The desire for high profits on behalf of a definite group of people leads to disappearing of fertile areas and whole mountains. This imp oses the sensible part of humanity to undertake measures to return part of the breached balance.
This elaboration suggests several innovative technologies for use in metallurgy and foundry as well as technologies for mechanical engineering, which ensure saving of material sources and achieve significant ecological effect on the environment.

The proposed technologies represent a complex of classical and modern methods for obtaining, processing and use of mineral and energy earth resources. Methods for utilization of some metal wastes to obtain fit for use products are also indicated
