Recycling of industrial goethite wastes by thermal

01-07-1995  The sample of P-Goethite was in part blended with the leaching residue enriched in lead. This mixture was prepared in order to ascertain the behaviour of lead under the thermal treatment; in fact some tests are outstanding for substituting the calcine and neutralizing agent with lead-rich oxides coming from another plant.

Goethite - Wikipedia

Goethite is a mineral of the diaspore group, consisting of iron oxide-hydroxide, specifically the "α" polymorph. It is found in soil and other low-temperature environments such as sediment. Goethite has been well known since ancient times for its use as a pigment. Evidence has been found of its use in paint pigment samples taken from the caves of Lascaux in France. It was first described in 1806 based on
