multigrades classification model of magnesite ore based onmagnesite is an important raw material for extracting magnesium metal and magnesium compound; how precise its grade classification exerts great influence on the smelting process. thus, it is increasingly important to determine fast and accurately the grade of magnesite. in this paper, a method based on stacked autoencoder (sae) and extreme learning machine (elm) was established for thehow to process lowgrade lead zinc ore by flotationapr 27, · tailings from the 6 cell regrind flotation machine contain the zinc values which are conditioned in a 5x5 superagitator and conditioner. the zinc is cleaned and recleaned in a 6 cell no. suba flotation machine.major mines projects cannington minethe processes for extracting the silver, lead and zinc from the ore involve grinding, sequential flotation and leaching techniques that produce highgrade, marketable lead and zinc concentrates with a high silver content. the cannington process plant has a demonstrated throughput capacity of 3.4 mtpa.zinc processing ores britannicazinc processing zinc processing ores zinc ores are widely distributed throughout the world, although more than 40 percent of the worlds output originates in north america and australia. the common zinccontaining minerals are the zinc sulfide known as zinc blende or sphalerite (zns), a ferrous form of zinc blende known as marmatite [(znfe)s], and a zinc carbonate known as calamine orassaying zinc determination methodsfeb 05, · the metals will be present as oxides. mix with 2 grams of powdered charcoal and charge into a blacklead crucible heated to whiteness, cover loosely, and leave in the furnace for about a quarter of an hour. uncover and calcine the residue, cool and weigh. the loss in weight multiplied by 8.03 gives the percentage of zinc in the ore. wet methodsestimated reading time 8 minsthe characterization of technological zinc cyclessep 01, 03· the rate of use of zinc has risen rapidly in recent decades. while the magnitude of use is less than that for other major metals (hassal and roberts, 98), world usage of new zinc continues a longestablished upward trend, as shown in fig. 1.in fact, roughly half of all the zinc employed during human history was mobilized and put into use in the 702 period.development of radiometric methods for exploration andto extract. grades of typical copper, g, nickel, lead, silver and zinc ores in australia and worldwide (shown for g only) in the period from 44 to 10 is shown in figure 2 . figure 2. decline in g ore grade in australia, brazil, canada, south africa, and usa from 44 to 10mineração determination of maximum zinc recovery of3 rem int. eng. j. uro reto 2(2) 32 apr. un. determination of maximum zinc recovery of vazante mine ore by flotation process sampling crushing grinding flotation the vazante industrial
