Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Crush and sort the ore with gold pan thankyou to the person above suggestion or heavy liquids Mix the ore with Sodium Carbonate and Sodium Chloride I ll have to double check the ratio s Sodium chloride is just a flux Heat in furnace to temperature I also have to check with oxygen lance This is based on a modern patent process

sulfi des pyrite sphalerite galena and gold in discrete quartz veins [1] Gold production is commonly done by the amalgamation and cyanidation process However due to the increased complexity of the polymetallic gold ore the direct cyanidation process has recently been yielding a low recovery of gold Therefore
·Modelling the behaviour of the ore in common beneficiation processes and applying mineral characterization can make a better prediction of the process with clear conclusions low risk and provide
·Ore deposit is the gathering of ore where ore is defined as a rock or sediment which contains sufficiently high levels of minerals that can be profitably extracted
·Abstract—Gold and silver are capable of forming stable natural compounds with different elements For gold 36 minerals are known 10 in the class Native metals intermetallic compounds and 26 in the class Sulfides selenides tellurides arsenides antimonides bismuthides For silver 194 minerals are registered in the MMA presented in 8
·The technological processing flowsheet for gold bearing ores varies widely The choice of a particular technological flowsheet depends on several factors including the nature of the gold in the ore especially its size and chemical composition the nature of the minerals associated with the gold the presence of other valuable components in the ore and the
·For instance a higher gold fineness with the chalcopyrite bismuth mineral galena pyrite association is related to chloride complexes at a higher temperature 275 °C to 350 °C whereas low but wide ranges of gold fineness with the sphalerite galena pyrite association correspond to bisulfide complexes between 150 °C and 275 °C Huston et al
·Spherical beads of gold remain behind and are difficult to dissolve Selenides behave similarly Metallic Gold Silver Roasting Metallic Gold Silver are fused at high temperatures forming spherical beads which are difficult to dissolve The temperature of the ore should never be allowed to exceed 1 000° for this reason
·The Garrcon gold deposit million tonnes of ore containing 636 000 oz Au 31 is located in the Garrison camp near the provincial border between Ontario and Quebec within a transtensional
