Old Pyrite Mine Theory - Oak Island Money Pit

On his second voyage to Frobisher Bay in 1577 he carried 200 tons of ore home on three ships. Encouraged, he returned with an even larger fleet and dug several mines around Frobisher Bay. On this voyage he returned with 1,350 tons of ore. Unfortunately, during the smelting of the ore, it was realized that the ore was iron pyrite. Therefore, almost worthless.

Pyrite - Wikipedia

The mineral pyrite , or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.

mine produced 5.5 million tonnes of iron sulphide ore at approximately 380,000 tonnes per annum. The ore mined had an average grade of 11% sulphur and was milled to produce a concentrate at 40% sulphur.

Iron ore is a rock containing iron, usually in the form of oxides (hematite, goethite and limonite), carbonates (siderite) or sulphides (pyrite). ii/ Classification of iron deposits 1/ According to Fe concentration, depending on the concentration of Fe element in the ore, there are three categories of ore: Poor ore: Fe ≤ 30%

9 Ore Deposits and Economic Minerals – Mineralogy

Pyrite and chalcopyrite, both sulfide minerals, are the primary copper ore minerals, but chrysocolla (copper oxide/hydroxide) and malachite (copper carbonate) are found and mined from oxidized ore zones. Although copper minerals are by far the most important ore minerals, the mine also produces lesser amounts of sphalerite (zinc ore), galena (lead ore), and molybdenite (molybdenum ore).

Pyrite — Wikipédia

Quality steel was being made in Prussia and Styria from siderite, so the thinking was that the presence of carbon in the iron ore would simplify the 3-step steel making process and allow a more direct, larger scale, and thus cheaper process. In 1867, the company name changed to The American Silver Steel Company. It greatly expanded the mining and built the railbed, furnaces and facilities whose ruins are …

Pyrite in Virginia

most pyrite mines in Virginia were in northern Louisa County Source: Laura Caswell, Gold-Pyrite Belt of Virginia. Pyrite is a mineral composed of two elements, iron and sulfur. One atom of iron combines with two atoms of sulfur to create iron sulfide (FeS 2). Because of its appearance and presence in metamorphic/volcanic rocks which can contain gold, pyrite is known as "fool's gold." Pyrite ...
