For many centuries the mining was mostly surface mining, particularly digging into the banks of the rivers and streams. From this comes the occupation "tin streamer," and was often practiced part-time by farmers and others to try to get a bit of cash. The invention of the steam engine and the Cornish pump in the 18th century made it possible to develop techniques of deep mining, where copper, tin, and other metals could be mined from depths approaching 2000 feet. Mines were often drilled along the coast with lateral arms tunneling out underneath the ocean. | For many centuries the mining was mostly surface mining, particularly digging into the banks of the rivers and streams.

By the early 19th century the landscape was covered with the stone engine houses where the engines running the pumps and other mining equipment were housed. Mining at that time was by far the most important part of the Cornish economy and the source of many jobs. The pay was good and the conditions were deadly. The average life expectancy for a below-ground miner was short, and an official report of conditions in the St Cleer mining district noted that the average age at death for a miner was 23 years. "Miner's lung" came from breathing the dust, and killed many men at a young age. The men operating the drills were paid very well, but were, with few exceptions, dead within 4 years. Children as young as 8 years were often employed in the mines. The young boys (mine-boys) often worked 12 hour shifts going up and down the ladders of several hundred feet to bring water, tools, powder, and other things to the miners who labored down below.

In the mining districts, there were large numbers of children of both genders employed in mining occupations. | ||

The Cornish pumps were exported to other places and were largely responsible for the demise of the water mills that drained the polders in The Netherlands. Dozens of windmills could be (and were) replaced by one Cornish pump. The mining of copper and tin elsewhere, particularly in the Western Hemisphere, could be done more inexpensively and led to the collapse of the mining industry in Cornwall in the latter part of the 19th century. This triggered the Cornish Diaspora, where a major part of the population left Cornwall for employment anywhere mines were operating throughout the world. | ||
The one major source of mining occupations through the 20th century and to the present time is the extraction of china clay in the areas near St Austell. This is sent upcountry and also exported to other countries for the production of fine china. There is also at least one slate quarry still operating at Delabole. | The one major source of mining occupations through the 20th century and to the present time is the extraction of china clay in the areas near St Austell.

Of course, the usual occupations found everywhere, such as farming, teachers, shop keepers, carters, civil servants, clergy, construction, masonry, innkeepers, grocers, dressmakers, butchers, and the idle rich are to found in Cornwall. Away from the coast, the illiterate who were not engaged in other occupations were usually agricultural laborers, eking out a marginal living. The last named will often be identified on a census record as "Ag lab." In the agricultural areas, boys (and sometimes girls) were frequently found living away from home as farm servants, often as young as age 10. The girls are also often found elsewhere as "domestic servants" where they earned their keep with another family. | Of course, the usual occupations found everywhere, such as farming, teachers, shop keepers, carters, civil servants, clergy, construction, masonry, innkeepers, grocers, dressmakers, butchers, and the idle rich are to found in Cornwall.
