Equally important for increasing the efficiency of nonferrous metallurgy is the transport infrastructure, since ore extraction, processing for the production of non-ferrous metals, further delivery of non-ferrous metals for the production of semi-finished products or finished products are related to transportation. In this regard, the main tasks set for the railway transport of Uzbekistan require a significant improvement in the technical and economic indicators of the railway industry as a whole for the further socioeconomic development of the country [4]. The construction of new railways and the electrification of railway sections, in accordance with the decrees and decrees of the President of the Republic of Uzbekistan [5–7], led to an increase in the total length of the main railways and the volume of freight traffic, which required the corresponding development of the freight wagon fleet. However, due to unsatisfactory condition and shortage of rolling stock on the railways of Uzbekistan, the fleet of freight wagons is not in a position to fully provide for an increasing volume of freight traffic [8]. The main factor leading to the critical condition of the inventory fleet of freight wagons is the annual cancellation of wagons without replenishment in sufficient quantities by freight wagons of modern designs, with modernized and upgraded units.","PeriodicalId":19653,"journal":{"name":"Nonferrous Metals","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2018-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44595915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, application of gravitation separation to this type of raw materials is of low efficacy, while cyanide leaching is limited by the presence of refractory minerals [2]. Besides, serious concern regar ding ecological safety of gold leaching promotes interest to cyanide-free alternatives, first of all, to ammoniathiosulfate leaching [3–6]. In contrast to cyanides, thiosulfates are biodegradable and low toxic that makes them applicable in-situ underground and heap leaching, moreover, they are cheaper and more efficient in case of carbonaceous ores and ores, containing copper, lead and zinc [4]. Depending on the type of raw material and leaching solution composition efficacy of ammonia-thiosulfate leaching reaches 50–95% [7]. However, optimization of leaching conditions is rather complicated due to the number of side reactions of oxidation and disproportionation involving thiosulfates [5]. Recovery of gold from ammonia-thiosulfate solutions is also not simple. Cementation is not efficient due to coprecipitation of copper and other metals [8]. Electrowinning allows in principle separation of copper and gold due to the difference in deposition potentials [9], but, in most cases, low purity product is obtain, moreover, low current efficiency markedly increases energy consumption [6]. Organic solvents extraction of gold with high efficacy (up to 97%) [10] is an example of expensive and limitedly applicable technology.
