A new generation of high-efficiency coarse and medium-fine crushers: CI5X series impact crushers
·In this paper a real world gold antimony flotation plant in Hunan province of China is discussed The simplified production flowsheet is shown in Fig consists of two main objectives 1 separate the gold from the raw ore in weak alkaline environment while the antimony particles are ensured to be non floatable; 2 separate antimony under a neutral or
·This took about 30 minutes g of the rich gold quartz mixture containing close to mg of gold was added; the synthetic gold quartz ore thus contained oz dwt gold per short ton Then sufficient minus 200 plus 325 mesh arsenic or antimony mineral was added so that the synthetic ore analysed % As or % Sb as the case
·Electrodeposited antimony can be treated with sulfuration volatilization technology which causes antimony to volatilize in the form of antimony sulfide During this process gold is enriched in the residue thereby realizing the value added use of antimony and the recovery of gold In this study the thermodynamic conditions of antimony sulfide were

·I Antimony Ore Dressing Various methods are commonly used for the ore dressing of antimony including hand sorting gravity separation and flotation
·At present antimony resources mainly exist in the form of antimony sulfide ore a the enrichment of the ore is mainly carried out by flotation [2] but a large amount of timony tailings is
·At the plant of the Consolidated Murchison Co in the Transvaal South Africa where a refractory high antimony gold ore is being treated flotation and cyanidation of the flotation concentrates and tailings are being practiced The association of the antimony and gold is very intimate and during 1946 while the antimony recovery amounted to
·FEED GRAVITY CONCENTRATE FINAL TAILINGS TREATED IN CARBON COLUMNS Sb2 VAPOR CONDENSED Fig 9 Consolidated Murchison flowsheet for antimony gold ore Swash 1986 Where the flotation concentrate is not leached a special treatment plant is used to grind and then leach the slag
·This molybdenum flotation circuit based on 250 500 tons per 24 hours is designed for low grade molybdenum ore having high grade streaks and with pyrite quartz is also basically sound for many other friable sulphide ores such as antimony silver and even some lead ores The basic ideas stressed in this moly flotation flowsheet are the
·Before the concentration of gold flotation was used to extract saleable 60% Sb antimony sulfide concentrate from the ore sample containing approximately 4% of antimony and 10 g/t of gold with
·The reagents system will be enhanced with new pumps and increased dosing rates to optimise chemical use The flotation circuit will produce antimony and gold concentrates which will be filtered and bagged for transport on site Life of Mine recoveries to payable are estimated to be % for gold and % for antimony Site infrastructure
The flotation concentrate is dewatered through thickeners and with filtration to produce a final antimony gold concentrate product which is bagged packed into shipping containers and shipped to customers overseas The feed to the plant during 2020 and 2021 was between and /t Au and to % Sb

·Disodium carboxymethyl trithiocarbonate D8 is an effective depressant for the flotation separation of stibnite and pyrite but its inhibitory mechanism is still unclear
Gold mineral flotation normally adopts one stage grinding flotation process but stages grinding and flotation for ore with uneven distribution Grinding fineness of gold For the gold wrapped in sulfide minerals sulfide ore reaches monomer dissociation; but for the gold with gangue grinding fineness should reach gold monomer dissociation
·03 Gold ore flotation concentrate roasting roasting and cyanidation process gold bearing antimony ores and high sulfur gold pyrite ores Roasting is used in the process to remove elements harmful to the cyanidation process such as arsenic and antimony The concentrator plant design is an important part of the plant construction It
·In summary a data driven based adaptive fuzzy neural network control strategy is developed for the antimony flotation plant The control strategy consists of FNN controllers data driven model and on line adaptive algorithm FNN is constructed to derive the control inputs of the antimony flotation process
·In this research the leaching of complex gold ore was studied using cyanide and glycine In the absence of glycine the gold dissolution increases from to % with increasing the cyanide
·antimony content starting from to 8 g / t for gold and from to 10% for antimony but on the other side it is difficult to cyanide Antimony m inerals are leached in alkaline cyanide
