How much and how many metals in mobile phones?

A mobile phone is typically composed of about 40% of plastic, 32% of non-ferrous metal, 20% of glass and ceramics, 3% of ferrous metal and 5% other [1]. Metals referred to in ref [1] are iron, copper (16 g), silver (0.35 g), gold (0.034 g), platinum and palladium.

Ref [2] mentions additionally the use of aluminium, magnesium, tin, cobalt, lead, nickel, cadmium and nickel. The document provides some guidance on best practices for the end-of-life treatment of mobile phones.

Ref [3] refers to total 60 elements being used in mobile phones, mentioning from the metals family (in addition to above metals) tantalum, neodynium and indium. It gives good information about the recycling value-chain and its challenges.

The above three paragraphs list a total of 16 metals used in mobile phones. Based on the total use of 60 elements, and the observation that only 20-30 of the world’s 118 elements are non-metallic, the number of metallic elements used in mobile phones could be as high as 30-40.
