Zinc sulfide restoration from the used television kinescopes and monitors of computers

One of the ways of restoration and use of secondary raw materials of waste for the decision both economic and environmental problems is described. Definition of optimum physical and chemical conditions of extraction of sulfide of zinc as secondary inorganic substance from the fulfilled cathodophosphor from the television kinescopes and computers monitors removed from the use from solutions of hydrochloric acid by method of chemical sedimentation for development power- and resource-saving technology of restoration of valuable inorganic substances from municipal solid waste is the aim of research. The foundation for scientific researches of the physical, chemical and mechanical properties of sulfide of zinc as secondary raw materials in comparison with zinc sulfide from pure primary raw materials is laid. The results of the study allow to reduce the irrational use of resources of inorganic substances, particularly of sulfide of zinc, to eliminate the burial of harmful substances from deviations which belong to the first and second class of danger, to increase the economic effect of the territory allotted for burial
