The problem.

[Brainheater]

I have spent some time thinking about the CO2 problem. The actual problem is that CO2 dissolved in water becomes an acid. This acid will and does dissolve copper oxide. To keep cO2 dissolved in water a pressure of at least 5 atmospheres must be maintained at room temperature. When the pressure is lowered the CO2 rapidly comes out of solution and the dissolved copper oxide is released,, plugging everything up. A column of water 300 ft deep will easily produce enough pressure at the bottom of the well to keep the CO2 in solution. The problem occurs when the solution is being pumped out. At some point we were shown a picture of a pump covered in copper oxide. This should be a solvable problem. Let's hope management are good problem solvers.

Why don't you ridiculous stubborn fools sell and buy TGB? A working mine with 4 properties including FLORENCE up the road that DOESN'T have any issues, which DOESN'T have the same geology and which DID test the project before blowing investors money.  Taseko will be producing 80 million lbs at $1 per pound, has a working cash flow positive mine, has a giant mine in the wings with

So what I think you're intimating is that the pumping is releasing the pressure to a degree that the copper oxide is being released and jamming the system. The gravity of the 300 ft column isn't sufficient to maintain the pressure.  So they need to either add downward pressure to the column or pump out just enough to start a syphon action. Of course , the syphon action is probably a

Wrong!  They pump in sulfuric acid which makes the carbonate rocks fizz. CO2 in water is Pepsi minus the sugar..it doesn't disolve copper or they wouldn't use sulfuric acid in the first place!  If you keep the CO2 in solution you cannot disolve the copper...hello?  There's no fix. It's the wrong rocks!

Metal: That was a remarkable diatribe. You strung 3 relative truthful sentences together that don't relate to the actual discussion and make a conclusion that's unsupportable by it's very nature.   If you were the leader of cavemen they would still be eating raw meat.

Metal you lost all credibility with the last post. A solution of water with sulphuric acid is pumped down the well. It reacts with the copper oxide and unfortunately the carbonite which is present. The reaction with the carbonite gives off CO2 which dissolved in water under pressure forms carbonic acid. Carbonic acid dissolves copper. When you see copper on roofs and gutters turning green it is

It would be pretty cool if they could time the pressure release to just prior to the pump so that the copper coming out of solution could attach to a removable filament or sleeve thereby bypassing the on-site electrowinning. Could turn carbonite into an advantage!

You just want to get the solution up to level ground while pressurized. Then it can drop into a tank where sulfuric acid is added and a small agitator can mix the tub. Remember the copper combines with the free ions of the acid at a molecular level. It will take a short while before it can be fully impregnate the acid solution and get pumped to processing.

Hahhahahaha!!  The "solution" will have NO COPPER IN IT!   You get copper to be a "pregnant" solution by disolving it in the ground with acid not by pumping water through the wellfield!  OMFG. Doesn't matter anyway as copper is hitting the skids now and the market is going to tank....MIN will be taking out a lot of new lows in the days ahead. Not only

77 people read this incredibly stupid post?  The world is doomed.  Hey stupid...if you have the "solution" at the surface in a "tub" why do you need to add acid to it?  How small is this small agitator?  A paddle? A spoon?  This has to be THE most ignorant post ever written ....just shows how ridiculously dumb you all are 

[metalhead666]

So why do they bother pumping SULFURIC ACID into the wellfield at all?  Why don't they pump carbonic acid in? Or Coca Cola?  Gezzus you people are so stupid! 

[metalhead666]

Copper turns green because it oxidizes...it reacts with oxygen not acid.  Go back to grade school science class. Do not pass go...lose more money with MIN stock

[Zurigo]

"anyone can google and confirm the above statements" do it, and you will find that Copper Carbonate is NOT solubole in water. So sadly your thesis is wrong. In case of MIN the only soluble Copper salt is Copper sulfate (the salt of the sulfuric acid and copper, and that is very good soluble in water). The sulfuric acid is neutralized with the Calcium carbonate present in the rock

[metalhead666]

Good post...MIN is the worst management I've ever known. Incompetent, arrogant, ignorant.  They went forward without knowing fully what they were doing and now they're paying the price...or rather stubborn investors are paying the price.  They will never be viable. You cannot change the fundamental geology which has proven to be their undoing.
