FINDING GOLD
By Sky
PANNING
Panning is the oldest and simplest way to find gold.
It is important that the dirt, stones and gold are in
the pan for a short amount of time so the gold can
sink to the bottom of the pan. Once done the sand
and dirt will simply wash away as you add water. As
your adding the water move your pan from side to
side or you can move it back and forward.
CRADLING
Cradling is a large wooden tool. The miners would
shovel a large amount of soil, gravel and sand into
the hopper. The hopper had a mesh at the bottom of
it allowing the gold to fall though but would catch
large pieces of rocks and sometime gold nuggets can
be caught in the hopper. When the sand, soil and
gravel are in the hopper a miner would add water
why another miner would rock it back and forth.
SHAFT MINING
People started shaft mining when a miner found small veins of
gold near the surface but the small veins of gold were also
under the ground. The miners started to dig holes about one
metre squared and fifty metres deep. To get the shaft to stay up
they would put timber along the shaft to stop it from falling.
They would need three to four miners working on one site, first
miner would be down in the hole putting soil into the bucket.
Second and third miner washes the soil into the cradle.
Puddling
Puddling separates gold from clay.
The miners would place the mixture
of clay and gold into a large
container and add water, they then
start to stir the mixture making the
clay dissolve leaving gold flecks
and sand at the bottom of the
container, the remaining mixture
then would be panned or cradled.
PUDDLING & MINERS PICK
Miners Pick
Miners pick is a tool to help
the miners break things
apart. This tool mainly breaks
solid pieces of rocks. Miners
pick also helps the miners to
dig there shaft when the
ground becomes to hard.
HOW DO PEOPLE F IND GOLD TODAY ?
The miners today use open-cut mining and under ground mining.
Open-cut mining, also known as open-pit mining, is the easy and
cheapest way to get gold out of the ground. Open-pit mining is
only used if the gold is close to the surface or if normal tunnel
type isn’t possible. Under-ground mining or known as under-
ground hard rock mining. The miners would dig a hundred metre
deep shaft this provides access for machinery in search for their
gold. The deeper the tunnels the deeper the risk of cave-ins and
collapses.
