Abstract:

Abstract The raw material base for many branches of the chemical industry is depleting; the issue of involving in the production of both raw materials with a low content of useful components and industrial waste becomes more and more urgent. Waste from production falls as a dead load on the cost of production of enterprises and often gives rise to a number of difficult-to-solve problems. This also applies to phosphogypsum ,i. e. a large-tonnage waste from the production of phosphoric acid by the sulfuric acid method. Phosphogypsum contains elements such as Ca, Mg, F, P, Si, Sr and rare earth e

Abstract:

Municipal landfills and open dumps with industrial waste are global issues which impact on the environment and on the health of populations. The production of phosphoric acid from natural phosphate rock gives rise to an industrial by-product called phosphogypsum, containing mainly dihydrated gypsum. Five tons of phosphogypsum are generated per ton of phosphoric acid production. The technology of roasting of phosphogypsum in a dehydrator, which is a mine, has been described in the article. Such reprocessing of the waste makes it possible to obtain a ready-made high-quality building material. Th

Abstract:

Phosphogypsum (PG: CaSO4·2H2O) is a waste product (or by-product) from the production of phosphoric acid, the main component in the production of concentrated simple and complex fertilizers. The world production of phosphogypsum exceeds 200 million tons per year. PG discharged into water bodies (seas, rivers) or disposed of in land dumps may contain elements (including heavy metals and radionuclides) in forms and concentrations that are toxic to ecosystems and human health, which raises concerns about its impact on the environment.

The growth of industrial production is accompanied by an increase in waste. In modern society, considerable attention is paid to the problem of processing man-made waste to obtain demanded products. Phosphogypsum is the main by-product of the production of fertilizers and phosphoric acid, it is a multi-tonnage waste, its storage leads to the withdrawal of vast territories from circulation.

Phosphogypsum is a residue obtained from phosphoric acid production. Phosphogypsum mainly contains calcium sulfate dihydrate and impurities originating from the source phosphate rock, including toxic trace elements and natural radionuclides. The phosphogypsum stacks occupy a large area and are an environmental issue today. The project “Phosphogypsum Processing to Critical Raw Materials”, currently realized at the Instit

The article presents the results of studies aimed at identifying the agronomic efficiency and application of phosphogypsum on soybean crops under irrigation conditions. It is shown that the combined use of irrigation with an i rate of 2760 m3/ha, mineral fertilizers and phosphogypsum in various doses provides a significant increase in yield and in soybean quality grain. The most optimal dose of phosphogypsum application (6 t/ha) was revealed. This dose provides soybean yield at the level of 2.53 t/ha.

In particular, calcium sulfide-based materials having luminescent properties are the object of intensive study due to the wide range of possibilities for their use. The alloying of the structure of calcium sulfide with cations of rare earth elements leads to the appearance of a glow having various colors. However, the high cost of such phosphorescent materials is due to the high chemical purity of the reagents required for their synthesis. The development of efficient methods for obtaining calc
