Greedy and in a hurry, they made do with simple yet effective tools. The gold panner patiently crouching alongside a river is symbolic of the Gold Rush, and yet gold pans were probably the most
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from ontheground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.
Hand tool Hand tool Iron and steel tools Iron technology was derived from the known art of reducing copper and bronze. The principal requirement was a furnace capable of maintaining a reducing atmospherei.e., one in which a high temperature could be maintained from a good draft of air. The furnace had to be tall enough to allow the iron to drop from the smelting zone and form a slaggy
The first mining efforts involved searching for the stones most appropriate for making tools. Primary stone tools are approximately 2.6 million years old, predating even Homo Sapiens. Hence, this time tracks the use of rocks as throwing weapons around 1.9 million years ago, following soon after by digging for the best cutting stones and stone
The 1849 California gold rush brought gold seekers from American and many countries to the San Francisco area. Excitement combined with new international tools and methods made the rush a time of

Panning was the oldest and simplest way to separate gold from surrounding rock. It was the most basic method to obtain placer gold. The basic procedure was to place some goldbearing materials, such as river gravel, into a shallow pan, add some water, and then carefully swirl the mixture around so the water and light material spilled over the side.
Slowgoing and dangerous it may have been, but ancient mining techniques were clever. The earliest mines sought cosmetic pigments for funerals. Picks and hammer stones are examples of stone age tools. Later, ancient man discovered metals which provided materials for superior weapons and tools.
