Koronadal City, Mindanao, Philippines ( 11:08:48 ThuMar 3 2011 )

I, in no way want interfere with the good news of dredging on the Klamath River or Oregon or raising money for the legal fund.

Anyway, I had a rice farm that needed harvesting and I was sitting on the back of my Honda Fit waiting for the tracer, (A machine that separates the rice from the stalk it grows on), and I looked off in the distance and saw the tracer being hauled by a Carabaw. Now this Carabaw, Water Buffalo, moves at it's own speed of about 2 miles an hour. So, I had plenty of time to wait since Carabaw and Tracer were about a 1/2 mile away as I looked over the flat rice paddies.

I grabbed the news paper, The Philippine Daily Inquirer, that I brought along. I was turning the pages and I came across a mining story and this was near the end of the story which stated, "Two weeks ago, they started testing a prototype machine, invented by a Danish geologist Philip Appel, that uses copper sheets and electricity to recover mercury buried in mine tailings (mine waste), to help start a cleansing drive. ??

That was only a highlight in the story because the main focus was in the title, BENGUET MINERS LEAD DRIVE VS MERCURY. The rest of the story, selected paragraphs, comes from the news paper article. "A group of pocket miners in Benquet is leading the campaign against the use of mercury in small-scale mining operations around the country. The process, called "whole ore amalgamation," involves pouring liquid mercury onto ore, which breaks apart rock and soil to extract gold. The Benguet Federation of Small Scale Miners (BFSSM) said the younger generation of miners has become conscious about the ill effects of mercury and returned to traditional mine processes, like panning and sluicing (a process using channels that regulate the flow of water) to extract gold. -..., that efficient gold extraction through mercury is driven by miners grappling with poverty or those who are lured by the gratification of easy money.

I am not sure if there is a lesson here?

Banguet is a land locked province in Luzon the northern most island. I am located in the southern most island of Mindanao.

Good information to know. Be careful in PI. I know it to be a whole different place. I was last there when we closed up Clarke and the anti-western sentiment makes it somewhere I would not want to re-visit.

God Speed.

Scooters great story. You're a lucky man, living at the same speed a water buffalo walks.

Mercury recovery from our CA mine tailings is a business venture of sound merit. Somebody is going to figure it out and make some money.

Actually
the copper sheet process is very old technology. They were called slick sheets. They are no longer used.

Basically because mercury has an ability to amalgamate with other metals, they would cover a sheet of copper with mercury. Then they would pass material over that sheet, and the fine gold would stick to it.

This new technology mentioned in the article is simply just taking a copper sheet, hooking it up to electricity to give it an ionic charge, then passing contaminated material over it. Mercury will amalgamate (stick) to the copper sheet and there you have simply removed some mercury contamination from the environment. This would not recover all the mercury, but it would remove most of the metalic mercury and thus prevent it from becoming reative mercury or methyl mercury.

It is great to see in other parts of the world that they will allow miners to help and clean up the mercury contamination from past mining practices, understanding that any mercury they remove is a huge environmental benefit.

Here in America, they want a piece of equipment that will not allow any mercury to be discharged to be developed for mercury clean up.

I don't understand why that is when common sense says that a machine that is 98 - 99 % efficient, (modern suction dredge) would be better than leaving the mercury in the river material to be continually spread farther by natural erosion and flood events. But that is American bureaucracy for you.
