The risks of metal contamination
The risks of unwanted metals in minerals and ceramics include value depreciation and then loss of usage value in the presence of impurities. The purchaser himself will therefore need to ensure that his product is iron-free.
The chip industry uses minerals among other things. If the mineral powder to be processed is contaminated with iron, it causes problems in production. This will also bring financial consequences: a high quality, pure raw material simply has a higher value.
In the ceramic industry, the presence of iron particles causes ‘black specks’ or rust particles in the glazing, and in finished goods, such as chamotte, quartz sand and feldspar.
But metal contamination also causes machine or production damage. In particular, broken-off teeth of excavator buckets can cause serious damage to breakers, the drums and the sieves. This results in production downtime and delay as well as the associated costs for repairs and reduced production capacity.
The intensive use of raw materials results in scarcity: high-quality raw materials are running out, as a result of which people are increasingly looking for raw materials that are less pure and of lower quality.
That is why we must remove even more metal particles.
This places high demands on magnetic separators to provide an ever-finer metal separation and also be easily cleanable.
