One good rule is to get your crusher as reasonably high as possible, as it is cheaper to pump your feed water a few feet higher so as to get a good clear run for your tailings, and also to give you room to erect secondary treatment appliances, such as concentrators and amalgamators below your copper plates and blanket strakes.
If the water in the stream is not sufficient to carry off the tailings, the battery should be placed at such a height as to leave sufficient slope for tailings' dumps. This is more important when treating ore of such value that the tailings are worth saving for secondary treatment. In this case provision should be made for tailings, dams, or slime pits.
He was lying hard on the place of his pain and rambling in delirium. "See, boys? Don't you see them?" "See what, my lad?" said the Boer simply, and he looked through the waggon window. "There's the head-gear of the mines. Look! the iron roofs are glittering. And yonder's the mine tailings. We'll be back in a jiffy. A taste of the whip, boys, and away!"
The cradle-box is about forty inches long, twenty wide, and four high, and it stands with the upper end about two feet higher than the lower end, which is open so that the tailings can run out. On the upper end of the cradle-box stands a hopper or riddle-box twenty inches square, with sides four inches high.
The eight per cent grade was steep enough to carry off boulders twice, three times, the size of a man's head when there was a force of water behind them. The last box was well over the river at a point where it was sufficiently swift to take off the "tailings" and keep it free.
Mac turned back, and consented to express his opinion of the money there was to be made out of tailings by means of a new hydraulic process. He was going to lend Kaviak to Sister Winifred again on the old terms. She'd take him along when she returned to Holy Cross, and Mac would go outside, raise a little capital, return, and make a fortune. For the moment he was broke hadn't even passage money.
On the application for a concession to treat tailings, 'Mr. Taljaard wished to know if the words "pyrites" and "concentrates" could not be translated into the Dutch language. He could not understand what it meant. He had gone to night-school as long as he had been in Pretoria, and even now he could not explain everything to his burghers.
Something like dismay was depicted on the men's faces when they heard this, but no one interrupted as he went on "We can do much better. Instead of treating those tailings by simply running them through the screens again and losing half the gold, we can build a proper roasting farnaoe, and then we can grind them, keeping the stampers for crushing alone.
All along the line of the Aunábé white sands, the tailings of natural sluices, have been deposited; the black sand sinking by its own weight. I was unable to find out the extent of the French concessions, and look forward to the coming day of compulsory definition of boundaries and registration in Government offices.
Boys, I proposes that as our new mate is finding the money to start the old battery again, and going even shares with us in the gold from the tailings, that we go even shares with him in whatever gold we get from the claims." "Right," was the unanimous response. And then they all came up one by one and shook hands with Grainger, whose face flushed with pleasure.
