“…In the territory of the branch of the NJFP "Kazphosphate" located in Taraz citythe mineral fertilizers plant-more than 10 million tons of waste from the production of phosphoric acid have accumulated. The accumulated waste is partially processed to obtain various commercial products for use in the form of fertilizers in agriculture [3,4]. Studies by scientists and manufacturers as well as laboratory experiments show that these industrial wastes are quite valuable secondary raw materials for the production of phosphate and complex phosphorus-potassium containing mixed fertilizers.…”

This article discusses the method of obtaining phosphorus-containing components from cottrel dust from the industrial wastes of the New-Jambul phosphorus plant. Accumulated industrial waste heavily pollutes the environment and has a direct impact on all living things. Therefore, their processing is of special interest for the state and grant programs have been allocated in order to obtain new valuable substances. In order to solve these problems, a number of experimental works have been carried out to study the chemical and mineralogical composition and chemical structures during the heat treatment of cottrel dust—the waste of phosphorus production. The optimal parameters of the process of obtaining mono-calcium phosphate from cottrel dust were determined and the process of crystallization of mono-calcium phosphate was studied. A method has been developed for obtaining a phosphorus-containing fertilizer based on cottrel dust from the industrial waste of the New-Jambul phosphorus plant by means of sulfuric acid solutions. The advantage of the resulting phosphorus-containing fertilizer is that it has a high solubility and digestibility of phosphorus plants. They are also high in phosphorus-containing substances that ensure the growth and yield of agricultural plants. The developed method for obtaining phosphorus-containing fertilizers is aimed at reducing the accumulated industrial waste, which in turn allows you to regulate and improve the environmental situation in the region.

“…A scanning electron microscope (SEM) is fundamentally a microscope generating on elctron beam scanning forth and back on a sample material. In morphological studies of before adsorption of CSAC adsorbent, the particle size was found 10 µm and randomness like structure (Smailov et al, 2022). But in the after adsorption of CSAC, the particle size was from 10 to 20 µm (Fig.…”

The work was investigated for the removal of Rhodamine B dye from an aqueous solution by the application of Chloroxylon Swietenia Activated Carbon (CSAC), which is obtained from Chloroxylon Swietenia tree barks because it’s harder and widely used for agricultural tools, timber, construction, and boat building. For the experimental methods, batch mode adsorption was used. The following operational parameters were followed: initial dye concentration, pH, and temperature for the adsorption of Rhodamine B dye. The adsorption equilibrium was attained after 75 minutes. The removal percentage of Rhodamine B dye was mainly dependent on the initial concentration of the dye solution. Three different adsorption isotherm models were used to calculate the equilibrium adsorption data. The diffusion of Rh-B dye inside the new formation of active sites occurred at maximum temperature, which predicted that the adsorption would be an endothermic reaction. The characteristics of CSAC were evaluated by SEM and FTIR spectroscopy.

This study analyzes the specific properties and technological parameters of gas emissions from chemical-energy processes [1], considering the volume and content of toxic components, as well as the operating experience of gas emission purification systems at existing phosphate plants. A three-stage system of apparatuses is studied for gas purification: an ensemble of single cyclones, foam aggregates irrigated with aqueous caustic soda solution. It is established that cyclones are the most suitable apparatus for dry gas cleaning, and that their diameter should be no more than one meter to increase the efficiency of cleaning. It has been demonstrated through scientific research that when cleaning phosphorite sintering gases, which have a volume exceeding the capacity of a single cyclone, it is necessary to use group cyclones. These are several cyclones combined into one group with a common hopper. It is recommended that the cyclone speed be increased by approximately 50% in comparison to the standard speed, which contributes to an increase in the efficiency of the separation of impurities in the purified gas.
