Human rights organisation Amnesty has accused Apple, Samsung and Sony, among others, of failing to do basic checks to ensure minerals used in their products are not mined by children.

In a report into cobalt mining in the Democratic Republic of the Congo, it found children as young as seven working in dangerous conditions.

Cobalt is a a vital component of lithium-ion batteries.

The firms said that they had a zero tolerance policy towards child labour.

The DRC produces at least 50% of the world's cobalt. Miners working in the area face long-term health problems and the risk of fatal accidents, according to Amnesty.

It claimed that at least 80 miners had died underground in southern DRC between September 2014 and December 2015.

It also collected the testimonies of children who allegedly work in the mines.

Paul, a 14-year-old orphan, started mining when he was 12 and told researchers: "I would spend 24 hours down in the tunnels. I arrived in the morning and would leave the following morning ... I had to relieve myself down in the tunnels … My foster mother planned to send me to school, but my foster father was against it, he exploited me by making me work in the mine."

UNICEF estimates that there are approximately 40,000 children working in mines across southern DRC.

In response to the report, Apple said: "Underage labour is never tolerated in our supply chain and we are proud to have led the industry in pioneering new safeguards."

It said that it conducts rigorous audits on its supply chain and any supplier found hiring underage workers is forced to:

• fund the worker's safe return home
• finance the worker's education at a school chosen by the worker or his/her family
• continue to pay the worker's wages
• offer him or her a job when he or she reaches legal age to work.

On cobalt specifically it added: "We are currently evaluating dozens of different materials, including cobalt, in order to identify labour and environmental risks as well as opportunities for Apple to bring about effective, scalable and sustainable change."

Samsung said that it had a "zero tolerance policy" towards child labour and that, it too, conducted regular and rigorous audits of its supply chain.

"If a violation of child labour is found, contracts with suppliers who use child labour will be immediately terminated," it said.

Sony commented: "We are working with the suppliers to address issues related to human rights and labour conditions at the production sites, as well as in the procurement of minerals and other raw materials."

Paradox?

The Amnesty report, which was jointly researched with African Resources Watch (Afrewatch), traced how traders buy cobalt from areas where child labour is rife, selling it on to firm Congo Dongfang Mining (CDM), a wholly-owned subsidiary of Chinese mineral giant Zhejiang Huayou Cobalt Ltd.

Amnesty contacted 16 multinationals who were listed as customers of the battery manufacturers, who in turn source minerals from Huayou Cobalt.

One company admitted the connection while four others were unable to say for certain the source of the cobalt they used. Five denied sourcing the mineral from the firm, despite being listed as customers in company documents and two others said that they did not source cobalt from DRC.

Six firms said that they were investigating the claims.

"It is a major paradox of the digital era that some of the world's richest, most innovative companies are able to market incredibly sophisticated devices without being required to show where they source raw materials for their components," said executive director of Afrewatch (Africa Resources Watch) Emmanuel Umpula.

"The abuses in mines remain out of sight and out of mind because in today's global marketplace, consumers have no idea about the conditions at the mine, factory and assembly line. We found that traders are buying cobalt without asking questions about how and where it was mined."

Mark Dummett, business and human rights researcher at Amnesty said that mining was "one of the worst forms of child labour".

"The glamorous shop displays and marketing of state of the art technologies are a stark contrast to the children carrying bags of rocks and miners in narrow man-made tunnels risking permanent lung damage," he said.

"Millions of people enjoy the benefits of new technologies but rarely ask how they are made. It is high time the big brands took some responsibility for the mining of the raw materials that make their lucrative products.

"Companies whose global profits total $125bn (£86.7bn) cannot credibly claim that they are unable to check where key minerals in their productions come from," he said.

It should be noted that the majority of the children working in the mining industry in DRC do not enter the underground mines but perform a variety of tasks on the surface, including scavenging for ore and sorting minerals that have been mined underground.
