The Qixia orebody is a complex lead zinc sulfide system with pyrite gangue and minor amounts of copper In order to improve the flotation results laboratory scale flotation testing of ore
Two flotation tests were conducted to duplicate the experiment Zinc sulfate ZnSO 4 and dextrin Due to the detection limit of the EDS analysis only the concentrations of zinc iron manganese and sulfur were taken into account Sphalerite composition was normalized based on the EDS data for zinc iron and manganese and a value of 33 wt
The properties and flotation behavior of coal pyrite were analyzed by the contact angle induction time and flotation tests The results indicate that compared with coal coal pyrite has a smaller contact angle and longer induction time
Sulfur removal from mineral concentrates is urgently needed given the increasingly stringent environmental regulations and low−sulfur feedstocks required by smelters However current desulfurization technologies suffer from considerably drawbacks such as high costs and harmful byproducts In this study we investigated the potential use and feasibility of
The particle size distribution of the residue indicated that the portion of thin particle with the size of 37 um reached and % of sulfur in the residue was distributed in this size fraction necessitating the flocculation flotation for recovering the elemental sulfur and sulfide minerals % of the sulfur was recovered with the
Almost all power plant units use pulverized fuel technology in which the content of the pulverized coal smaller than 75 μm size is typically 75% Ulusoy and Igathinathane 2016
According to the data obtained from batch flotation tests the maximum recovery of total sulfur was achieved when the operational parameters were set to the PAX dosage 200 gr/t MIBC dosage 150 gr
The characteristics of each image are strongly correlated with the sulfur flotation process conditions and the froth depth so that digital image processing technology can be introduced into the
The content of sulfur in iron ore concentrate is the major problem of steel making industries In this paper the reverse column flotation operation is used to reduce the amount of sulfur of the
The sulfur grade and concentrate recovery increased by % and % respectively and the lead and silver recoveries from the tailings increased by % and % respectively compared with those obtained by using a conventional flotation process These test results indicate that ultrasonic pretreatment is an effective technique for
Exploring new ways to acquire niobium resources is essential to resolve niobium supply risks due to the fact that at present 99% of niobium is controlled by only two countries In the present work a flotation technique was applied to separate niobium from low grade niobite ore To maximize the utilization of the original ore resources pre flotation was conducted to
The content of sulfur in iron ore concentrate is the major problem of steel making industries In this paper the reverse column flotation operation is used to reduce the amount of sulfur of the
Yunnan Jinding Zinc Industry Co LTD YJZI has carried out the semi industrial flotation tests of the tailings with a 200 t/d capacity in 2022 A lead‑zinc flotation products was obtained and the recoveries of Pb and Zn were about 45% and 75% respectively data not reported The volatilization behavior of lead zinc and sulfur from the
In this research a Test Rig Flotation Column was used to reduce the ash and sulfur content for two Colombian coal samples Guachinte and Yolanda
The sample with smithsonite and cerussite as the main valuable metal minerals is a carbonate hosted lead zinc ore in the current study Hydrothermal sulfidation of oxidized zinc lead ore was carried out with a particle size of 74 to 58 μm and the mole ratio of sulfur and zinc of at 453 K 180 °C for 240 minutes and 73 pct zinc and 86 pct lead sulfidation fraction were
The Qixia orebody is a complex lead zinc sulfide system with pyrite gangue and minor amounts of copper In order to improve the flotation results laboratory scale flotation testing of ore
Effective desulfurization of high sulfur bauxite is one of the major problems in the alumina production industry To overcome this a novel nanoparticle collector NC to improve the
A spectrum of flotation methodologies such as cationic reverse flotation and reverse flotation are prevalently applied in addressing IOTs The general flotation scheme of IOTs is shown in Fig 6 This technique is particularly conducive for IOTs with complex compositions albeit demanding a significant initial iron grade warranting a pre
The Froth Flotation Machine is universally used for all types of flotation problems This machine finds a wide acceptance due to its flexibility in construction which allows the machine to be adjusted to handle pulps with divergent physical characteristics as well as the common and intricate metallurgical problems which confront the present day operator
ton of sulfur as hydrogen sulfide gave satisfactory results at the test plant of the Magma Copper Company on malachite Sodium sulfide has been tested at the concentrators of a number of the larger copper companies having been added to the flotation machines or to conditioning tanks before flotation as tests showed that better sulfidlzing of the
A high sulfur content is one of the challenges in the processing of refractory bauxites in China The high carbon content of bauxite makes it more difficult to deal with Desulfurization and decarbonization are the critical issues in the efficient exploitation of high sulfur bauxite resources An experimental study on the removal of sulfur and carbon in high sulfur
