Mining 101
Gold ore, which contains gold, and iron ore, which contains iron, are wellknown examples, but rock that contains silver, copper, tin, zinc, aluminum or rare metals like manganese and nickel that have become much talked about in recent years is also called ore. "Mining" is the work of digging up ore from the mineral deposits where it is found.
How lead is made
Mining the ore. 1 The first step in retrieving leadbearing ore is to mine it underground. Workers using heavy machinery drill the rock from deep tunnels with heavy machinery or blast it with dynamite, leaving the ore in pieces. Then they shovel the ore onto loaders and trucks, and haul it to a shaft.

For the vacuum tube (as probe sample) I connected all the prongs together with the single leadin wire, burying the tube. I left ¼ inch between the soil and the bakelite base. This probe (wired side "up") was placed in a section of ground which lay among the loveliest trees on our property, directly amid the moist dark green lawn.

Sep 09, 2019 · The probe remained stranded in low Earth orbit (311 × 104 miles or 501 × 168 kilometers) and telemetry ceased by Aug. 27, 1961, when the main battery went dead. The spacecraft reentered Earth's atmosphere three days later.
Staking a claim: Deepsea mining nears fruition
May 14, 2014 · Deepsea mineral reserves exist in three crude forms: as SMS, as polymetallic nodules (also known as manganese nodules), and as cobaltrich crusts. These can produce everything from industrial metals like copper, lead and zinc, to more precious metals like silver and gold, as well as some increasingly important rare earth elements.
