response surface methodology for optimizationof copper

Response surface methodology is used to optimize the leaching process for refractory flotation copper tailings. The proportion of the refractory combination oxide copper (chrysocolla) is 64.84%. At present, few studies have examined the leaching of chrysocolla. In this study, we examine the effects of several variables, including the amount of concentrated sulfuric acid, leaching temperature

feature optimization for atomistic machine learning yields

Machine-learning of atomic-scale properties amounts to extracting correlations between structure, composition and the quantity that one wants to predict. Representing the input structure in a way that best reflects such correlations makes it possible to improve the accuracy of the model for a given amount of 2018 PCCP HOT Articles

flotation fundamentals-mineralprocessing & metallurgy

Apr 29, 2018 · In Flotation Fundamentals, the presence of the collector significantly increases the contact angle, indicating enhanced particle-bubble contact.Typical materials demonstrating hydrophobicity will have contact angles between 45 and 90 degrees. The separation of one component from another by flotation depends on the relative water-wetting ability of the surfaces of the various particle components


The department of “Processing“ at the HIF deals the optimization of classical flotation techniques, amongst other things. Learn more about the different flotation processes and their areas of application in the article “A fine future – Flotation in times of circular economy and energy transition“

optimization of miningmineral processing integration

Traditional ore-waste discrimination schemes often do not take into consideration the impact of fluctuations of the head grade, which have on the performance of mineral processing facilities. This research introduces the use of target grades for processing destinations as an alternative to cut off grade-based methods and models, in each processing destination, the losses due to deviation from

inverse molecular design usingmachine learning

Jul 27, 2018 · The discovery of new materials can bring enormous societal and technological progress. In this context, exploring completely the large space of potential materials is computationally intractable. Here, we review methods for achieving inverse design, which aims to discover tailored materials from the starting point of a particular desired functionality. Recent advances from the rapidly growing
