Lithium has a low melting point, high boiling point, most negative potential, light mass, etc.,It is widely used in new energy vehicles, nuclear industry, aviation, medical, and other fields. Lithium is the most important basic raw material for new energy industry.,be known as "21New Energy for the Century". In order to accelerate the realisation of the strategic goal of "Carbon Neutral, Carbon Peak".,China has vigorously developed the lithium new energy industry,Demand for lithium feedstock is increasing year on year,Lithium's growing strategic position,A new round of competition for mineral resources has been launched[. Currently,The main sources of domestic lithium resources are salt lake lithium and ore lithium. Ore lithium mainly includes lithium pyroxene, lithium mica, lithium feldspar, lithium iron mica, lithium muscovite, lithium aluminium phosphorite, etc.. To ensure stable market supply of lithium raw materials,Lithium extraction from lithium mica,Has become an important way to obtain lithium feedstock,Yichun area in Jiangxi has the world's largest associated lithium mica mine[12]. During the beneficiation of lithium mica,Belt filters are commonly used in the dewatering of lithium mica concentrates.,Concentrate moisture is generally greater than18%,There are features such as high moisture of lithium mica concentrate, large equipment footprint and low processing efficiency. A mineral processing plant in Yichun area adopts a company's production ofFFPDewatering of lithium mica concentrate by horizontal quick opening filter presses,It has the characteristics of small equipment footprint, high processing efficiency and low moisture of lithium mica concentrate.,at the same time,It can reduce the transport cost of lithium mica concentrate and the drying cost of downstream lithium carbonate plant. This paper focuses onEffect of filter cloth type, cycle time, working pressure, type of filter aid, and dosage of filter aid in lithium mica concentrate on the moisture of lithium mica concentrate in a fast-opening filter press.
1The test specimens were taken from a lithium mica concentrate of a mineral processing plant in Yichun area.,The results of multi-element chemical analyses of this lithium mica concentrate and the results of sieve analyses of the lithium mica concentrate are shown in Table1wristwatches2The From the table1wristwatches2knowable,This lithium mica concentrateLi2Oquantity contained1.71%,Al2O3quantity contained29.34%,SiO2quantity contained47.60%. Lithium mica concentrate particle size<75μmContent as a percentage of32.79%,<25μmContent as a percentage of14.63%,The dewatering process is difficult and the concentrate moisture is high when using traditional belt filter dewatering.2FFPHorizontal quick-opening filter press introductionQuick-open horizontalFilter press is a high capacity filter press.,Mainly used for solid-liquid separation.FFPQuick-opening horizontal filter press is shown in the figure.1Shown. Operating time,The main steps are as follows.
1)infeed:The material is pumped to each filter chamber of the filter press.,Until it's completely full.
2)filtration:Rising feed pressure,Cake formation on the surface of the filter cloth,The filtrate is discharged through a collection channel.
3)squeezes:Diaphragm after extruded media enters each chamber,The diaphragm squeezes the cake between the filter cloths.,Force the filtrate through the filter cloth.
4)air dryness:Compressed air passes through the filtrate channel on the diaphragm side,Blow-dry the moisture in the filter cake to a minimum. During the drying process,The filter cake keeps the diaphragm squeezed,The filter cake can be maintained without cracking.
5)Pipe flushing, blowing:Residual slurry and water in the pipeline is cleaned and disposed of.
6)Diaphragm Release:The compressed air in the diaphragm is completely released.
7)pancake unloading:approximate30sshort time,All the filter cake is discharged at once. When the filter plate set is fully opened,The filter cloth is vibrated to ensure complete cake discharge.
8)Filter cloth rinsing:After unloading the cake,The filter cloth is flushed by a shower pipe mounted on top of the filter plate set. This ensures the removal of residual filter cake from the surface of the filter cloth.,and ensure good running conditions for the next cycle.Quick-open horizontalFilter presses have the following advantages:
1)High efficiency of equipment operation,Short technical time for opening and closing plates, etc.(<30s).
2)Weighing system installed,Measurement of the feed volume at any time,and automatically adjusts operating parameters;
3)Filter plates in accordance with European quality standards,Reliable quality, removable and replaceable edge wear parts,No need to replace the entire filter plate;
4)Automatic vibration of the filter cloth after discharging the cake,Helps to unload the cake and remove residual cake crumbs,Completely eliminates the need for manually assisted unloading,Avoid residue being trapped between the filter plates,Causes deformation of slurry or filter plates;
5)High degree of automation,the scene (of the incident)PLCcompatibility withDCSsystem connection,Observation of equipment operation status and remote start/stop can be realised in the central control room.;
6)Low running costs,Fully automatic operation of the whole plant,The site is largely unmanned,It can save more labour cost for customers.
3Results and Discussion A lithium mica concentrate from a beneficiation plant in the Yichun area was used as the object of study.,Lithium mica concentrate particle size<75μmquantity contained32.79%,Slurry concentration55%.
