Waste-Free Technology for the Production of Building Materials by Mining and Processing Plants

The purpose of the study is to develop a waste-free technology for the production of building materials by mining and processing plants. The emission spectral analysis method was used to determine the chemical composition of mining waste and substantiate the possibility of using waste as raw material for the production of new products – building materials. The results of the analysis of the chemical composition of mining waste showed the possibility of using them as raw materials for the production of fiberglass. The method of waste utilization with the production of type D fiberglass for mining and processing plants is proposed. The method includes extraction of rock from the dumps of stone crushing plants, fine grinding of waste to a fraction of 0.1–0.5 mm, extraction of iron (III) oxides on a magnetic separator, adding B₂O₃ and MgO in appropriate proportions, and supply of raw materials to the glass furnace for the production of fiberglass. Waste-free technology for the production of building materials by mining and processing plants, which includes the production of gravel, the production of fiberglass based on the proposed method of waste disposal, and the production of pigment for paints from extracted iron oxide (III), is proposed.
