The gold was brought to the surface as small particles embedded in lumps of quartz. The quartz was then crushed into a fine dust by stamping batteries in a stamping mill. A stamping battery contained a row of stampers. On the bottom of each stamper was a heavy piece of steel. Each stamper was connected to the cam shaft which was turned by a water wheel. The steel shoes went up and down between wooden guides and pounded the quartz which had been fed into steel boxes underneath the stampers. Ideally the stamping batteries would work 24 hours a day.
After crushing, the quartz dust was mixed with water to make sloppy mud which then ran down sloping tables, called concentrating tables. On top of these tables were copper sheets coated with mercury Daniel Carlson Jersey , which attracts gold. The gold particles stuck to the mercury, and could be collected from there.

Manchester United can still win the Premier League title, despite their stuttering campaign so far, after a 1-0 victory at arch-rivals Liverpool on Sunday moved them within seven points of the top spot, manager Louis van Gaal said.
The win moved United within sight of leaders Arsenal, who are level on 44 points with surprise front-runners Leicester City after sharing the points in a 0-0 draw at Stoke City.
Asked if United were still in the title race, the Dutchman told a news conference, "It is seven points and seven points Linval Joseph Jersey , we can overcome that.
"This game shall give a big boost to the players, to the fans, to everybody in the environment of Manchester United and we have to continue, of course.
"That's not so easy, and we have seen that also today, but we can do it because we show every week that we can do it."
Van Gaal has many critics among United fans but has given them at least four reasons to smile since taking over at Old Trafford, with four wins in four league games against Liverpool.
Sunday's victory in the northwest -derby at Anfield - thanks to Wayne Rooney's 78th-minute volley - -completed a second successive league double over Liverpool for Van Gaal following -United's 3-1 win at Old Trafford in September.
Last season United beat Liverpool 3-0 at home and 2-1 away Harrison Smith Jersey , and he was delighted after Sunday's victory in a drab game lifted United back up to fifth in the table. "In the second half we played much -better and kept the ball better and created chances, and Wayne Rooney makes the fantastic goal again," Van Gaal told Sky Sports.
Rooney's strike, an athletic hooked volley after Marouane Fellaini's header bounced back off the crossbar, was the one moment of true class in a game of few scoring chances.
Rooney has now scored in four successive games and took his league tally for United to 176, the record by one -player for one club in the Premier League era, passing Thierry Henry's -previous mark of 175 for Arsenal.
