Skarn-type deposits show complex mineralogical and textural relationships because of the variety of geological processes involved in their development. Mineral associations can be further complicated by supergene leaching and oxidation. Consequently, hydrothermal alterations constitute complex geochemical signatures to be analysed under a number of factors in these mineralised systems, which are conclusive in vectoring these types of deposits. This study is proposed in order to understand these alterations and to propose their usefulness in the exploration of Cu-Zn skarn deposits. The methodology of bibliographic research and case studies was used, from three main sources of data: information from the Mesozoic sedimentary belt of the Inter-Andean Cordillera and the Yauli dome, case studies from different parts of the world and analysis of the geological, magmatic and petrological conditi...

Geometallurgy is defined as the study of the genesis of minerals with respect to the performance of their metallurgical processing. The construction of geometallurgical models is of the utmost importance for the technical-economic evaluation of the deposit. The robustness of the model depends on the number of resources invested to generate potential information that will serve in decision making. The relevance of the geometallurgical model has a high value in mining management, which serves as an instrument for the planning, exploitation and design of metallurgical processes according to the type of deposit. Using the information to maximize economic performance in concentration processes has enormous potential and challenge for plant operators. This article will discuss the use of data analysis and its applications in several successful cases for porphyry-type deposits, taking...

Concern about reducing greenhouse gases drives us to migrate to the use of clean energy. Therefore, a large investment in the green economy modality is necessary, since the brown economy does not include sustainable development (Campos, 2010).
