Examples of ore

• The methods of assaying were supposed to determine the quantity of a given metal in an ore or alloy with one or more other metals.

• Probably the latter, since there was no reason to keep the source of the non-existent 'ore' a secret after 1578.

• Different panels would reflect the various stages of mechanical production and assembly, from mineral ore in the soil to finished product, driving into the sunset.

• The easily worked oxidised ore was largely depleted and the underlying sulfide deposits were proving difficult and costly to treat.

• Thus, the markets for ores and minerals in situ do not suffer from the kinds of failure we are alluding to in the text.

• These compounds were found in the extraction of metals from ores, assaying, and the reextraction of metals from alloys.

• Later chapters cover ores and waste products, diamonds and their histories and the nature of the planetary bodies of the solar system.

• Subidioblastic titanite (commonly overgrowing allanite or ore) and ore phases are small (< 1 mm) yet numerous.
