There is no control over the stockpile area
Bad control over operating conditions such as the quality of input materials
Bad operation performance
Not optimal extraction
High bauxite consumption
High bauxite ratio
Too much residue
High loss caustic
High caustic consumption
High caustic ratio
To maintain the dissolution ratio due to fluctuating material input so that the solvent flow rate is also unstable:
Over pressure so much impurity in extract
Bad filtration process
High impurities
High lime consumption
High lime ratio
Bad settling process
Not optimal extraction
Too much mud and dirt
High flocculant consumption
High flocculant ratio
The heating steam input is often reset to maintain the temperature
High steam consumption
High steam ratio
tank levels can increase drastically so it needs to be balanced with increases in equipment frequency
equipment such as pumps, compressors, thickeners etc. operate at high frequencies
High electricity consumption
high electricity ratio
