Henry Richard Hancock (1 April 1836 – 14 January 1919), almost invariably referred to as "Captain Hancock", was a mine superintendent in Moonta and Wallaroo, South Australia. He was noted for his business acumen and the respect with which he was held by both workers and mine owners.

History
Hancock was the third, and the eldest surviving, son of George Hancock (c. 1803 – 22 February 1848), wheelwright and Wesleyan Methodist lay preacher and his wife Sarah Hancock, née Lipson (c. 1799– ), who married on 1 June 1830 and lived in Horrabridge, near Tavistock, West Devon.

He received a good education and at the age of sixteen began work at the nearby copper and tin mines, learning every aspect of their operation.
In 1858 he was brought out to South Australia as superintendent of the Wheal Ellen, a small silver-lead and copper mine near Woodchester, South Australia, between Strathalbyn and Callington. 
It is reported that his abilities were noticed by (later Sir) Thomas Elder, who after that contract was over (c. January 1862), recommended to Hancock that he not return to England, but make his fortune in South Australia, sentiments echoed by Robert Barr Smith.

By 1863 he was in charge of the assay office of the copper mine at Moonta, where a rich find had been made a few years earlier. He was then made surveyor, and made himself thoroughly conversant with the layout of the underground workings. In July 1864 he was made superintendent of Moonta Mines.

Hancock and Captain William Arundel Paynter (1819–1873) invented and patented an improved "jigger" (a device employing water and agitation to separate ore from the lighter stuff). Their invention not only required less labor to operate, but wasted less copper-bearing ore, and as the Hancock jig was in use worldwide for many years.

When the richest ore had been mined and there was much talk of closing the mines at Moonta and nearby Wallaroo, Hancock was put in charge of both operations, and by diligent management kept both operational. When he retired, to be replaced by his son H. Lipson Hancock JP, he had been superintendent of the one for 34 years and the other for 22.

He retired in August 1898 and left Moonta the following October, when he and Mrs Hancock were accorded an elaborate farewell.

Their home "Ivymeade" in Burnside was advertised for sale in 1902, and became the residence of Dr. Alfred Edward James Russell, who died there in 1905. It was again advertised in 1907. Captain Hancock died there, as did his wife Loveday Hancock, after which it was finally sold by auction in 1934, to Captain W. B. White.
