Leaching and solvent extraction purification of zinc from
An integrated hydrometallurgical process was used for the zinc leaching and purification from a zinc ore containing 9.75 wt% zinc. The zinc minerals in the ore were hemimorphite, willemite, andElectrolytic manganese anode slime (EMAS) contains many Mn resources, and efficient Mn leaching is the key to realizing its high-value utilization. In this study, the effects of Fe2+ concentration, H2SO4 concentration, liquid–solid mass ratio, reaction temperature, and current density on Mn leaching efficiency were investigated.

Energy saving: EU action to reduce energy consumption
New targets adopted by the Parliament in July 2023 set a collective reduction in energy consumption of at least 11.7% at EU level by 2030 (compared to the projections of the 2020 Reference Scenario ). EU countries have to save on average 1.5% per year. Energy savings should start with 1.3% a year until the end of 2025, This research concentrates on Uruguay considering pollution in the country is a major economic and environmental concern that affects not just the nation but also the Latin American region.

Metallurgy Leaching, Extraction, Refining Britannica
Metallurgy Leaching, Extraction, Refining: Oxides are leached with a sulfuric acid or sodium carbonate solvent, while sulfates can be leached with water or sulfuric acid. Ammonium hydroxide is used for native ores, carbonates, and sulfides, and sodium hydroxide is used for oxides. Cyanide solutions are a solvent for the precious metals, CAST ( 1999) and Wilkinson ( 2011) found that ruminants converted potentially human-edible feeds to animal product with similar efficiency to monogastric livestock, mainly because human-edible feeds comprised a low proportion of the total feed input to the system ( Table 1 ).

An overview of rare-earth recovery by ion-exchange leaching
To evaluate the commercial potential for the recovery of REE s from ion-adsorption deposits in a systematic manner, a standardized procedure for REE leaching was developed previously. Using this procudure it was found that, regardless of variations in ore origin and REE content, all REE consistently reached peak extraction levels under The grain parameter in the leaching process was 0.26263 and the apparent activation energy E=17.12 kJ/mol. Tellurium could be pre-leached from the telluride-type gold flotation concentrate through the Selective Pre-leaching of Tellurium From Telluride

TENORM: Copper Mining and Production Wastes US EPA
Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice.Days of Leaching 80 70 60 50 40 30 20 5 10 15 20 25 30 Copper Leached (%) Fig. 1a: Industrial Column Leaching Oxide Ore Leach time is 70% of control 34% more copper leached 28ppm LixTRA™ Control Results From Figure 1 (a-d) the beneficial effect of using LixTRA™ can be observed when leaching; a) an oxide ore b) a secondaryLixTRA™ Novel Copper Leach Technology BASF

Energy conservation
t. e. Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through efficient energy use
