Mineral Processing Plant Design & Construction Example

Economics of Flowsheets

Metallurgical Recovery, which consists of the percentage of mineral saved, must not be confused with economic recovery which covers the percentage of the gross value of an ore recovered as a net profit. In other words, in commercial practice the prime object is the highest possible net profit over and above all costs. Thus a […]

Mineral Processing and Extractive Metallurgy

Mineral Jig

The first objective of Mineral Processing and Extractive Metallurgy is to remove the Mineral as soon as freed and as coarse as possible” is the first rule in treating complex ores. Ores containing two or three metals have been satisfactorily treated for a number of years. Today, however, ores containing as high as four, five […]

Mineral Processing and Ore Dressing

Sub A Flotation

Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs. While the smelter recovered […]

Solvent Extraction Training SX Course

The Process of Leach SX EW

Solvent extraction, the process of extracting a specific metal valve from a solution to concentrate and purify that metal is a multistage process involving liquid ion exchange. In the first stage the metal value, in this example copper, exists in the aqueous leachate as an copper ion. The aqueous leachate is mixed with a organic […]

Recycling Sand from Foundry Casting Molds

Recycling Sand from Foundry Casting Molds - 911Metallurgist

The flowsheet shown in this study is particularly adapted to the requirements of the average foundry to reclaim foundry sand for re-use. Any foundry whose new sand delivered costs is too high should seriously consider reclamation with the flowsheet as illustrated. This reclaimed sand is usually equal to, or better than the original sand. Foundry […]

How to Operate a Thickener

Typical_gravity_thickener

Running a thickener properly isn’t as easy as it looks. True enough, a thickener doesn’t make a racket like a ball mill, or spew out froth like a flotation machine, or bounce up and down like a jig, but down inside that big tank there is a lot going on just the same. You, as […]

How to Operate a Grinding Circuit

How hard a ball mill operator has to work depends partly on himself, and partly on the kind of muck the mine sends over to the mill. In some plants, the ore may change two or three times a shift, and a ball mill operator has to keep on his toes. That’s why it would […]

The main idea in collecting the information you’ll find in the following discussion was to help you, as a flotation machine operator. Regardless of how much or how little you know about it, the ideas you’ll find here can help you do a better job, if you want them to. Naturally your company is anxious to […]

Mineral Processing and Extractive Metallurgy Methods

Mineral Processing

A successful search for and development of a new mineral deposit rests not only in its discovery but also in economical processing of the ore. Via the Science of its engineering, Mineral Processing and Extractive Metallurgy allows the evaluation of metal recovery Methods laid-out or expressed as a process flowsheet. The challenge of discovery and development, […]
