New Zealand Antimony was forced into voluntary liquidation in 1892. A smaller New Zealand syndicate then took over the mine and formed the Star Antimony Company in 1892. This operation survived until July 1901, when it too foundered. Several groups then attempted to revive the mine up until 1908 but failed.

Mt Stoker deposit, also known as the Mt Stoker Antimony Mine, near Hindon (Rowe, 1881a) consists of an auriferous quartz lode with pyrite and some stibnite. The lode is 5.5 m wide and dips 45o to the northeast. The deposit was worked intermittently up

The lode is 3 to 5 feet thick. The antimony lode was discovered by Caudwell and Spearing (surnames) while prospecting for gold around the late 1870's. Several bags of test ore were sent to Boston, London, and Melbourne, however only results from Melbourne were returned showing antimony at 47%.
antimony. New Zealand Occurrence, Past Production and Imports Stibnite has been recorded from many localities in New Zealand (Figure 1), principally in association with mesothermal gold-bearing quartz lodes in Paleozoic to Mesozoic greywacke and schist, although it also occurs in epithermal quartz veins and sinters associated with late Cenozoic volcanism. Tetrahedrite,
01.05.2004· Mining for antimony began in the hills above Endeavour Inlet in 1874, following discovery of stibnite bearing veins in 1873 (Johnston, 1993). In 1875, a smelter was erected to process the mined ore, on an alluvial terrace at the base of the hills about 1
01.11.2004· Historic antimony mining at Endeavour Inlet, New Zealand, was developed in a stibnite-rich mesothermal vein system hosted in a km scale shear zone in metasedimentary schist. The schist contains calcite, and all waters have pH between 7 and 8.
Antimony in the New Zealand environment Dave Craw Geology Department, University of Otago, Dunedin, New Zealand Abstract Sb has similar chemical behaviour to arsenic, in that it has 3+ and 5+ oxidation states, and forms oxyanions in solution.
02.03.2020· The Stibnite Mining District in Idaho — which incidentally was our stopgap source of antimony during World War II — is home to at least 180 million pounds of antimony. And while production in the...
The antimony mine opened and closed many times in the following years. It was taken over by the Endeavour Inlet Antimony Company in 1883 and new processing works built 500m from shore. Three more companies and several groups tried to keep it going but by 1908 all had failed. More attempts were made in 1927, 1933 and a new prospector’s licence
01.05.2004· Antimony bearing residues (up to 17 wt.% Sb) at an historic smelter site in New Zealand have become variably oxidised over the past 100 years. Coarse (cm scale) tailings are almost fully oxidised as they allow free and rapid movement of rain water through their pore spaces. Smelter slag forms hard massive blocks with only incipient surficial oxidation. Sulfide-rich sand tailings still contain
Antimony in the New Zealand environment Dave Craw Geology Department, University of Otago, Dunedin, New Zealand Abstract Sb has similar chemical behaviour to arsenic, in that it has 3+ and 5+ oxidation states, and forms oxyanions in solution. Sb occurs at low background levels in New Zealand rocks (typically 0.01-0.1 mg/kg), distinctly lower than arsenic (2-20 mg/kg). Sb is readily mobilised
01.11.2004· Historic antimony mining at Endeavour Inlet, New Zealand, was developed in a stibnite-rich mesothermal vein system hosted in a km scale shear zone in metasedimentary schist. The schist contains calcite, and all waters have pH between 7 and 8. Underground tunnels (adits) have largely collapsed, but two adits provided access to waters which have interacted chemically with mineralised
Mining industry. The mining industry takes products from under the ground. In New Zealand these include gold, ironsand, coal, petroleum and limestone. Most are used within New Zealand, but exports are worth over a billion dollars a year.
Mining in New Zealand began when the Māori quarried rock such as argillite in times prior to European colonisation. Mining by Europeans began in the latter half of the 19th century.. New Zealand has abundant resources of coal, silver, iron ore, limestone and gold.It ranked 22 in the world in terms of iron ore production and 29th in gold production.
The first record of primary antimony mining in Alaska was the Sliscovich Mine about 30 miles northeast of the famed gold mining town of Nome. First opened in 1906, Sliscovich was positioned to provide a domestic source of antimony at the onset of World War I, which sparked stibnite mining across much of Alaska. "WWI created considerable demand for antimony," James Barker, who investigated much
Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was
In light of this, it is hoped a new antimony roaster being built in Oman could help diversify supply of the metal away from China, which dominates mining and refining, especially as the ongoing trade war between the US and the Asian nation intensifies. Outlook for antimony. China currently accounts for over 90% of antimony supply. However, this has been declining in recent years, due to older
"Antimony Speculators Lose Out" Speculators who tied up large sums of money in Chinese antimony, which is used in the making of ammunition, in the hopes of reaping great profits are now ruing
