A method for calculating the proportions of minerals in igneous rocks based on the chemical analysis is proposed.
New methods for purposeful modification of its mineral and chemical composition have been developed on the basis of experimental studies and physical-chemical modeling processes: magnetic separation of crushed raw materials; crystallization and gravitational differentiation of melts; melting in oxidizing, reducing and inert atmospheres; leaching gabbro-basalt raw materials with mineral acids.
The methods to apply currently unused portion of gabbro-basalt raw materials are proposed to produce the following: stone ceramics of various purposes with a matrix that facilitates the technology, makes it less energy-intensive, and also expands the raw material base and the range of products produced; – finely dispersed powder by the method of ultrasonic dispersion to produce ceramics with higher values of density, hardness and acid resistance than natural basalt; anticorrosion coatings made from fine powder and applied to metal surfaces by using high-temperature inorganic binders.
It was developed a friction material on the basis of stone ceramics, chopped continuous basalt fiber and phosphate matrix, this friction material can be used for the manufacture of brake pads and vehicles clutch plates as well as aircraft brake pads, drilling rigs and lifting gears.
It was developed physicochemical foundations of pyro- and hydrometallurgical processing methods of wastes materials by using gabbro-basalt raw materials. (in Russian)
