Taptic Engine will use recycled rare earth elements, Apple said today. It is reported that one of the rare earths used by Taptic Engine is rare earth.IPhoneOne fourth of the total rare earth used.
Rare earth is the abbreviation of a group of metals. It contains 17 elements such as lanthanum, cerium and praseodymium in the periodic table of chemical elements. It has been widely used in many fields such as electronics, petrochemical and metallurgy. At present, China dominates the processing of these primary minerals.
Apple said the use of recycled rare earths would help ensure supply stability. In fact, the recovery efficiency of rare earth is not high. Statistics show that for every 100,000 iPhones recovered, only 32 kg of rare earth is extracted from them. In consumer electronics products, rare earth mainly exists in micro loudspeakers and actuators. Because these parts are too small, it is difficult and expensive to collect and recycle them.
In addition, Taptic Engine will use recycled rare earths from an external supplier rather than from the iPhone. Apple did not disclose the identity of the supplier or what products it would use to recycle rare earths.
