But the goal is to combine recycled metals bought from suppliers with those taken from old Apple products returned by customers.
As lofty as Apple's recycling goals are, though, the company admits it isn't quite sure how it's going to achieve it.
Apple is looking to build on this sustainability achievement by pledging to encourage its entire supply chain to move to 100 percent renewable energy.
Apple also hopes to use only renewable energy in all its facilities, including stores and factories - it's now at 96% renewable usage - as well as encouraging its supply chain to only use renewable energy and ensure all its products are supplied in 100% recycled paper packaging. The company is set to announce a new, unprecedented goal for the tech industry, "to stop mining the earth altogether". Apple accounts for 70 percent of the company's sales of camera modules. The Cupertino company had taken the same approach with the iPhone 7 past year to make it easier for consumers to use a device that lacks the 3.5mm headphone jack.
Apple's next iPhone could have some big design tweaks in store, if a recently leaked schematic is any indication.

Other mined materials used in Apple products include aluminum, copper, tin and tungsten.
Taiwanese original design manufacturer Wistron - with which Apple has a contract - will begin assembling the iconic phones at its unit in a Bengaluru suburb, the officials told ET. "So we're a little nervous, but we also think it's really important, because as a sector we believe it's where technology should be going". That production method also emitted 60% less greenhouse gas.
Still, Apple's promise is a step in the right direction, even if the company still doesn't know how exactly it will come to fruition. But Apple said that seven major suppliers have now pledged to power their Apple production entirely with renewable energy by the end of next year. In March 2016, Apple announced that all 242 of the smelters and refiners that supply it with conflict minerals are a part of an auditing program conducted by the Conflict-Free Sourcing Initiative (CFSI), a third-party association.
