Colonial Weaponry Boosted by Mesoamerican

Even Spain at that time had not produced the metal domestically for centuries, relying on imports from central Europe. In Mesoamerica, they had to depend on local smelters, furnace builders, and miners to produce the essential material. Those skilled workers, in turn, were able to bargain for exemption from the taxes levied on the other indigenous people.

Metal mobilization from base-metal smelting slag

01.04.2008· This paper examines slags from the Dolores and Santa Ana smelters, which operated from 1850 to 1885. These two sites were chosen because major industrial facilities currently occupy the surface of these slag dumps, which potentially enhances metal mobilization due to sewage infiltration. Around 650,000 t of accumulated slags are located in the study area, which occupies the coastal area

Copper Smelting - an overview | ScienceDirect

2.1.1.6.1 FeO–Fe 2 O 3 –SiO 2 Slags. It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO 2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces now use basic refractories. Viscosities of slags are important, because they allow the selection of an oxide melt

This work reports the chemistry and mineralogy of mineral efflorescences associated with slag deposits at the historical Río Tinto smelter site, southwest Spain. The slags have been subject to weathering since dumping in the 19 th and 20 th century, and a series of evaporative mineral efflorescences has been observed. The efflorescences commonly occur as powdery or cemented salt precipitates

smelter of copper slag in spain. Oct 02, 2020· Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
