The quartz, as extracted from the reef, is cobbed down with hammers to about pass a 1 Jinch ring, and is then carefully handpicked, all stone showing visible gold, sulphurets or any other favorable indications being sent to the mill and the rest being thrown away.
The solid wastes, both 'coarse' and 'fine', produced by a mineral processing plant are dumped at sites close to the minemill complex. A common aspect among a great majority of mineral beneficiation plants is that they produce significant quantity of 'tailings' in the form of 20 to 40% slurry (Figure 1).
Production of tailings. The disposal of tailings is commonly identified as the single most important source of environmental impact for many mining operations (Vick 1990). This is not surprising when considering that the volume of tailings requiring storage can often exceed the insitu total volume of the ore being mined and processed.

An alternative to pond disposal of washingplant slurries is dewatering of the slurry at the preparation plant and subsequent disposal of the fine refuse with coarse refuse. This practice is gaining increasing use, as a greater number of washing plants now incorporate closed processwater loops.
The objective of tailings management is to confine the mine tailings and provide for their safe, longterm disposal. Tailings are stored in engineered structures called tailings impoundment areas, which can be created through the use of dams, berms, and natural features of the mine site such as valleys, hillsides, or depressions.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing Less wear takes place in rubber lined mills. it was not until the industrial revolution and the invention of steam power that an effective ball milling machine could be built.
extraction plant, producing the sand dumps (Crown Gold Recovery, 2003). However, the introduction of the tube mill forced a move away from amalgamation since the slurry was coarser and less suitable to such treatment.

Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings.

Tailings Management is a fundamental component in the design and operation of mining projects in Canada. Potential environmental and socioeconomic considerations need to be balanced to ensure disposal and storage of tailings occurs in a sustainable and responsible manner.
Paste tailings disposal. Paste tailings are defined as tailings that have been significantly dewatered to a point where they do not have a critical flow velocity when pumped, do not segregate as they deposit and produce minimal (if any) bleed water when discharged from a pipe (figure 1).
In 1976, several large tailings of South Africa began to tailings disposal, and has been profitable until now; In a Canadian gold tailings disposal project, a period of processing 50,000,000 tons of tailings, the average grade of tailings is 0.52 grams / tons, and finally, the average recovery rate was as high as 60%.
