The efficient recovery of chromite fines is a significant challenge in the mineral processing industry due to their small particle size and high dispersion. This study explores the application of the SLon high gradient magnetic separator (HGMS) for the beneficiation of chromite fines. Through a series of controlled experiments, the effectiveness of the SLon HGMS in improving the grade and recovery rate of chromite fines was evaluated. Key parameters such as magnetic field intensity, feed rate, and particle size distribution were optimized to achieve maximum recovery. The results demonstrate that the SLon HGMS significantly enhances the separation efficiency of chromite fines, achieving high recovery rates with minimal loss of valuable minerals. This technology offers a promising solution for the economic and sustainable processing of chromite ore, contributing to the overall efficiency of mineral resource utilization.

The cuttability of rock formations is a critical factor in optimizing mining and excavation processes, directly impacting the efficiency, safety, and cost-effectiveness of such operations. This study focuses on the cuttability assessment of Upper Red Sandstone using a Small-Scale Linear Rock Cutting Test (SSLRCT). The SSLRCT provides a controlled environment to simulate rock cutting and evaluate key parameters such as cutting force, specific energy, and tool wear.

Upper Red Sandstone samples were subjected to the SSLRCT under various conditions to measure these parameters and analyze their correlation with rock properties such as uniaxial compressive strength, density, and mineral composition. The results indicate that the specific energy required for cutting increases with rock strength and density, highlighting the importance of geological conditions in planning rock excavation operations. The study also explores the wear patterns on cutting tools, providing insights into tool life and replacement schedules.

Rock sawing is a critical process in various industries, including mining, construction, and quarrying. Understanding the mechanical properties of rocks, such as brittleness, is crucial for optimizing the efficiency of rock sawing operations.

A comprehensive dataset of rock samples with varying brittleness characteristics is analyzed. The study employs statistical methods and regression analysis to quantify the connection between brittleness indexes and specific ampere draw. The findings provide valuable insights for selecting suitable rock types for sawing operations and optimizing cutting parameters, ultimately enhancing the efficiency and sustainability of rock sawing processes.
