At this link is a magnificent collection of photos of some of the largest mining open pits and meteorite craters. The text that accompanies the photos is prejudiced: the message is that mining open pits have forever changed the landscape–although craters have had similar impact. You are left wondering what the writers really think. (more…)

It costs between $1 and $40 a ton to build, operate, and close a mine tailings facility. That is as specific as I was able to be when answering a question today in response to an enquiry from Australia. There is a surprising paucity of data out there on the cost of tailings management.

But we have no data-base on tailings costs. (more…)

A fine testament to the engineers who study rock and soil slope stability in the open pit mine context. (more…)

Vale wants to close the mine as it is presumably not making money, inflation in Argentina is 25 % per annum, and Vale did not get tax breaks they were seeking. (more…)
Just returned from a trip to a fly-in, fly-out mine where the temperatures were down to minus forty and fifty. The only consolation for the extreme cold was the company. Here are a few word pictures of some of the people I chatted to. I set them down here as a way to represent the extremes of jobs and careers in the mining industry, and specifically in the far north.
