Scientific researches in new directions in the field of calcium metallurgy are reviewed. It is concluded that lack of competitiveness in the global market of Russian production of electrolytic calcium compared with calcium production in China, obtained by the metallothermic method, even despite its purity and quality due to certain changes in the structure of consumption. Productions comparison in environmental terms is mentioned separately. Low and high temperature processes for the preparation of calcium by aluminothermics are considered, what provides an overview of ways to use the obtained passing products for the implementation of the non-waste production principle, in particular the use of aluminum silicates in the production of high-grade cement, the production of flocculants, getting graphite as a product, including pencil lead. It should also to be considered the possibility of using in the technology as a raw material so-called limestone screenings, is a waste of burning limestone, which is offered at bargain prices. It is concluded that a high readiness for the introduction of metallothermic mode technology of calcium production and the interest of all rate company-producers from small to large and all forms of ownership. This highlights the fact that the investigated at present, including in the framework of public-private partnerships, innovative ways of producing cheap calcium such as aluminothermy, silicothermic and carbothermic methods allow to solve the problem of import substitution in Russia in particular industries.
