The sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores. However, it generally has higher production costs and with acid treatment is more expensive to build than a chloride plant. But the latter may require the construction of a chloralkali unit.
Aug 16, 2018· Aluminum recycling process. The process of recycling aluminum is tremendously efficient. Only five percent of the energy invested in creating fresh supplies of aluminum is required to recycle the same amount, and because aluminum is infinitely reusable there is no loss of quality once the recycling process is finished [4].
