Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
Dewatering and solidliquid separation is an important part of any mineral processing plant. It spans a range of stages, from feed preparation to concentrate handling and tailings disposal. Our experience in this area is extensive, and includes thickener and filter technologies from testing to
rock fill for backfilling, (Tesarick et al., 2003). This paper discusses the similarities and differences between the underhand cut and fill mining methods used at the Lucky Friday, Stillwater, and Galena Mines in the northwestern US (Figure 3). Each mine has developed its underhand mining system to accommodate the unique
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water .

the Mineral Processing Technology Roadmap, addresses those technologies leading to mineral processing improvements which may apply to one or to multiple mining product areas. Many other steps in the mining process are identified in the vision but are not addressed in this document.
Cut and fill stoping is a method of underground mining used in vertical stopes and in mining high grade irregular ore bodies. The rock mass surrounding the ore deposit is also usually weak unable to support loads over an extended stoping height.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Apr 07, 2015018332Chapter 5 Introduction to Hydraulic Fill Hydraulic fill is a class of mine fill types that are delivered as high density slurry through boreholes and pipelines to the underground mine voids. The name is derived from the water born delivery method. Hydraulic fill is most commonly prepared by dewatering and desliming mineral processing waste
