This paper describes the results of a beneficiation study conducted on low-grade fluorite ore. The was aimed at development suitable process to produce chemical grade concentrate. representative sample ore up-graded by leaching and flotation process. important parameters froth were optimized obtain highest recovery A single-factor variation method applied get optimum conditions rougher concentr...

We propose a novel method enabling autocompletion of chemical flowsheets. This idea is inspired by the text. represent flowsheets as strings using text-based SFILES 2.0 notation and learn grammatical structure language common patterns in transformer-based model. pre-train our model on synthetically generated flowsheet topologies to grammar. Then, we fine-tune transfer learning step real topolog...

Abstract Waste pharmaceutical blister packages (WPBs) are a source of solid waste, which composed plastics and aluminum, therefore acting as potential for secondary aluminum. The structure WPBs makes the recycling aluminum notably more complex than typical recycling. Currently, WBPs disposed municipal waste; thus, is lost from circulation during incineration. In this work, three types were stud...

The processes of extractive distillation and heteroazeotropic mixtures containing water a high-boiling component (propionic acid, acetic 1-methoxy-2-propanol) are compared. Entrainers declared in the literature as effective agents for these were selected separating agents. A process simulation AspenPlus V.11.0 is made. Parametric optimization carried out column operation parameters (number stag...

The article examines the possibility of extracting sod fuel peat to replace imported coal. A possible raw material base is considered for producing molded solid peat-based in permafrost conditions. production products form proposed as an option. experimental work on drying shows that can be extracted and dried standard moisture content conditions northern Yakutia. flowsheet from lake by hydraul...

To protect natural resources and avoid environmental pollution, an effective method is proposed to recover tin (Sn) from waste printed circuit boards (WPCBs). In order realize the efficient recovery of Sn, it necessary study effects experimental parameters on Sn leaching understand kinetics processes. The statistical mathematical technique (response surface methodology (RSM)) was used interacti...
