More than you ever needed on Heap Leach Pads; thanks to the many experts in the field
I have blogged a lot about heap leach pads. I have posted some semi-serious and serious writings on TechnoMine at the page called LeachMine. And now an EduMine course, Heap Leach Pads. Here is the introduction and summary I wrote for it:
This course is about heap leaching: the design of heap leach pads; the mechanics of preparing the mined ore for placement on a pad; the construction processes involved in placing materials on pads for leaching; the operation of heap leach pads, including the application of fluids that liberate the metals in the ore; the physics and chemistry of the seepage of fluids through the ore; and the ultimate closure of the heap leach pad when mining ends.
Taken together, the blog postings, the TechnoMine articles, and the EduMine course, and you have a set of information. Not perfect; not totally comprehensive; but a start. Thus my request: please help me gather together as much about heap leach pads as we can. If you have comments on my writings, information that I have not recorded, case histories to share, or ideas and proposals for continuous improvement, please pass them along.
Let me acknowledge here the many people and companies that have set me through the fascinating world of heap leach pads: Ian Hutchinson of SES who started it all; Adam Whitman of Meridian Beartrack who challenged me; and the many scientists and engineers who have written so extensively and so well about heap leach pads–not the least of whom is Vector Engineering. Without them, I could not and would not have been able to generate what I did. They deserve any credit available; and you should consult them, not me, if you need more information, or innovative solutions.
