The Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow.
Authier Lithium Project Sayona Mining acquired 100% of the Authier project in July 2016 for CAD$4 million. The Company's primary strategy is to focus on completing the studies required to commence the development of the project.

Overview Oceanic is focused on the development of the Ungava Bay iron properties. These properties comprise 3,703 claims over three project areas, namely Hopes Advance, Morgan Lake and Roberts Lake, which are located over 1,568 km 2 along the northern extension of the Labrador Trough in the Nunavik Region of northern Quebec.
THE BASIC PROCESSES OF GOLD RECOVERY INTRODUCTION. Man has held a fascination with recovering and acquiring gold almost since the beginning of time.
Minerals produced in Nevada and their uses. For more than 150 years, Nevada mining has produced minerals that are key to an innovative and advanced society.
Mining as an industry underwent dramatic changes in medieval Europe.The mining industry in the early Middle Ages was mainly focused on the extraction of copper and iron.
Coal mining - Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.
Mining: Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure.

MINING . This page primarily focuses on metallurgical mining, though many of the terms, processes, and concepts are the same within the non-metallurgical extraction industry.
A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back ...
Heavy machinery is wanted in mining for exploration and development, to remove and stockpile overburden, to break and remove rocks of various rigidity and hardiness, to process the ore and for reclamation efforts after the mine is closed.
