Using illegally mined tin to produce the iPhone
Apple might have used illegally mined tin from Indonesia to manufacture its iPhones and some other products. At least, that’s what the international environmentalist group Friends of the Earth said recently. According to the group’s website, tin mining on Bangka Island, in Indonesia, has been connected to “the destruction of tropical forests, coral reefs and fishermen’s livelihoods”. They also call […]

Levin Grindability Index Test Method & Procedure
The Ball Mill Grindability of ores is generally determined by the Bond standard grindability index test method. However, this test and procedure is not applicable to fine materials such as sands; the grindability of fine materials must therefore be determined by a comparative grinding method, for which a reference material of know grindability is required. Suitable […]
Three quarters of the world’s mining companies are based in Canada but there aren’t enough overseas laws
Did you know that Canada is the home of 75 percent of the planet’s mining companies? That’s right! At least, according to the Foreign Affairs, Trade and Development of Canada. After all, it’s Canada that is keeping the mining industry “glued” together, hosting almost 1,300 mining companies that are investing hundreds of billions of dollars […]
