In the two Haciendas of the Company, La Purisima and La Soledad, amalgamation is but little employed. The ores are usually smelted, and in this process great use is made of the tĕqŭesqūitĕ, (carbonate of soda,) from La Sălādă, which is employed as a dissolvent. The lead ore (or Grētă) used, is brought from Măpĭmī, or Cuēncămē, (on the frontiers of Dŭrāngŏ and Chĭhūāhuă;) the charcoal from the Mēzquītāl, or the Mēzquītĕ woods belonging to the Hacienda of Mŭlērŏs, on the road to Durango.
