Description
Существующие способы переработки р да металлургических продуктов, в особенности содержащих несколько цветных металлов, по свойствам своих соединений затрудн ющих их раздельное получение, как медноцинковый концентрат, смешанный окисленный и сульфидный продукт и др., весьма сложны и страдают р дом недостатков.The existing methods of processing a number of metallurgical products, in particular containing several non-ferrous metals, by the properties of their compounds making it difficult to separate them, such as copper-zinc concentrate, mixed oxidized and sulfide products, etc., are very complex and suffer from a number of disadvantages.
За последние годы имели место попытки к улучшению этих процессов , но они почти во всех случа х привели к усложнению пирометаллургического процесса.In recent years, there have been attempts to improve these processes, but in almost all cases they have led to the complication of the pyrometallurgical process.
Дл улучшени и упрощени процесса при одновременной максимальной его гибкости автор предлагает следующий метод переработки этих продуктов.To improve and simplify the process while at the same time maximizing its flexibility, the author proposes the following method of processing these products.
Переработка сульфидов цветных металлов ведетс в печи типа ватержакета , примен емой дл осуществлени фьюминг-процесса, котора питаетс твердым пылевидным сырьем, подаваемым в печь совместно с пылевидным твердым топливом и воздухом, вдуваемым в имеющуюс там расплавленную массу. Печь соедин етс с другим устройством типа передового горна или отражательной печи, куда вывод тс газы и образующийс избыток расплавленной массы. В этом устройстве обработанна расплавленна масса , отстаива сь, расслаиваетс на штейн и шлак, металл и шлак и пр., хот не исключено частичное расслаивание в ватер-жакете.The processing of sulphides of non-ferrous metals is carried out in a vaterjack type furnace used for the implementation of the fuming process, which is fed by solid pulverized raw material fed into the furnace together with pulverized solid fuel and air blown into the molten mass present there. The furnace is connected to another device, such as an advanced hearth or reflective furnace, where the gases and the resulting excess molten mass are removed. In this device, the treated molten mass, settling, is stratified into matte and slag, metal and slag, etc., although partial stratification in a water jacket is not excluded.
Такое устройство в отличие от конвертора обеспечивает сохранность аппарата, посто нный состав отход щих газов и непрерывность работы.Such a device, unlike a converter, ensures the safety of the apparatus, a constant composition of the exhaust gases and continuity of work.
Шлаки при этом получаютс во всех случа х бедные металлом и заданного состава за счет регулировани количества вводимого в печь топлива, которое может быть самым разнообразным . Коэфициент использовани тепла достаточно высок и утилизации тепла отход щих газов вполне достаточно дл удовлетворени потребности в энергии дл подсушивани , измельчени и вдувани шихты.In this case, slags are obtained in all cases poor in metal and of a given composition by regulating the amount of fuel introduced into the furnace, which may be the most diverse. The heat utilization factor is high enough and the waste heat utilization is quite sufficient to meet the energy demand for drying, grinding and blowing the charge.
В случае медной и в особенности медно-цинковой плавки получаетс возможность перерабатывать без пылеобразовани тыс чи тонн шихты в одном аппарате в сутки.In the case of copper and, in particular, copper-zinc smelting, it is possible to process thousands of tons of the charge in one apparatus per day without dusting.
При желании можно вместо щтейна получить сразу металл при отвальных шлаках как результат воздействи If desired, instead of barn the metal can be obtained immediately with waste slags as a result of exposure

PL70803B1 (en) | The method of processing lead dust from copper smelters in a shaft furnace. The subject of the invention is a method of processing lead dust from copper smelters into metal lead and copper-lead stone in a furnace. In the process of copper production, as a by-product in the final stage of dust removal in electrofilters, two types of lead dust, i.e. shaft dust in which the lead is in the form of lead sulphide, and blister dust in which the lead is in the form of lead sulphate. An exemplary chemical composition of lead dust from copper boots in percent by weight is the copper charge in the briquetting process of copper concentrates and then smelting the briquettes in a shaft furnace to obtain copper matte. The lead contained in the charge is concentrated again in the shaft dust during the melting of the charge in the shaft furnace and partly in the copper matte, and then concentrated in the converter dust during the conversion of the copper matte. Part of the lead from the charge passes into the slag and is discharged from the production cycle with a problem. The main disadvantage of this method is the continuous recycling of lead in the production cycle. Lead dust from copper smelters is processed in shaft furnaces for the production of copper matte in to recover the copper they contain. This method consists in adding dust to copper, as a result of which there is a large loss of this metal in the waste slag. Another method consists in calcining and sintering the lead dust on a sinter belt, including roasting and sintering galena, and processing the resulting sinter in a shaft furnace for producing lead. The disadvantages of this method are the difficulties in sintering the charge containing lead dust from copper smelters and introducing into the production cycle lead, large amounts of copper and bismuth, which are harmful admixtures in the lead production process. Moreover, the processing of lead dusts with the above methods does not allow for the recovery of other accompanying metals, especially rhenium. The object of the invention is to overcome these disadvantages by using a process for the processing of lead dust from copper smelters which enables the simultaneous recovery of copper and lead and other accompanying metals, in particular rhenium. The method of processing lead dust from smelters developed according to the invention is as follows. The lead dusts are briquetted or pelleted on disk granulator to give granules of 10 - 30 mm. In the pelleting process, the addition of binder, for example sulphite slurry, is used in an amount of 5 to 15% by weight, based on the granular dust. Then the briquettes or granules are melted in a shaft furnace without their initial roasting, using technological additives such as: iron scrap in the amount of 3-12%, quicklime in the amount of 2-4% and slag obtained in the stone converting process in an amount of 8-20% by weight in relation to the melted dust. An exemplary chemical composition of the convertible waste used as a technological additive in the process of smelting lead dust in percent by weight is as follows: 4.92% of copper, 45.70% of iron, 1.69% of sulfur, 1.11% Lead, 25.28% Silica, 4.02% Calcium Oxide, 1.72% Magnesium Oxide, and 2.11% Alumina. The size of the pieces of iron scrap, quicklime and converter slag to be loaded into the shaft furnace should be 10-80 mm, preferably 25-50 mm. The products obtained by the method according to the invention of processing lead dust from copper smelters in a shaft furnace are: crude lead containing at least 92% by weight of lead, copper-lead stone containing 10-20% of lead, 10-25% lead and 8-30% sulfur. % by weight, a zuzel containing no more than 5% lead and 1% by weight of copper, and shaft dust. Volatile metals or volatile metal compounds, especially rhenium, are concentrated in the shaft dusts, which allows for further processing of these dusts in order to recover rhenium. The remelting products are continuously discharged from the furnace into the clarifier, where the lead, copper-lead matte and slag are separated by gravity. In order to reduce the lead content in the copper-lead matte and to reduce the sulfur content of the crude lead, the iron scrap is added to the settler in an amount of 3-6% by weight in total in relation to the amount of lead, copper-lead matte and slag. . The sludge is discharged through the overflow opening, while the lead and copper-lead stone are discharged separately through the lower drain opening. The crude lead is further processed in lead smelters, while the copper-lead matte is processed in converters for the recovery of copper by known methods. The process of smelting lead dust from copper smelters in a shaft furnace can be carried out both without and with the use of hot blast, enrichment of the blast with oxygen and adding coal dust through nozzles. In order to ensure the proper course of the decomposition of lead sulphates, the lead dust smelting process in the shaft furnace should be conducted so that the height of the charge layer in the furnace does not exceed 2 meters, while the temperature of the top gases should be 150 to 300 ° C. The use of the method according to the invention enables the economical use of lead dust from copper smelters by simultaneously recovering lead and copper therefrom, and enables further processing of secondary shaft dusts for the recovery of rhenium therefrom. Claims 1. The method of processing granulated or briquetted lead dust from copper smelters in a shaft furnace, characterized in that lead dust, in which lead is in the form of lead sulphides and sulphates, is melted directly in a shaft furnace, without preliminary - they are in the form of oxides in the roasting process. 2. The method according to claim A process according to claim 1, characterized in that in the process of smelting lead dust in a shaft furnace, technological additives are used, such as iron scrap in the amount of 3-12%, preferably 4-8% by weight, quicklime in the amount of 2-6%, and preferably 2-6%. 4% by weight and converter zuzel in the amount of 8-20%, preferably 10-12% by weight, based on the melted lead dust. | |
