The Metallurgy of Cyanide Gold Leaching An Introduction

Oct 20, 20140183;32;Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.

Leaching (agriculture)

In agriculture, leaching is the loss of water soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.

Effects of High pH Levels. Acid loving plants prefer a pH of 5.0 to 5.5, ornamental plants and lawn grasses like a pH of between 5.8 to 6.5, as do vegetable plants. Also, water garden plants like a pH between 6.2 to 7.4. Over time, calcium carbonate leaching from a concrete water garden pond can raise water pH to above 7.5.

Wetlands and Water Quality Purdue Extension

Algae and floating plants absorb nutrients from surface water. These plants essentially convert the wetland into a quot;nutrient sink,quot; by taking nutrients from the water and sediment and retaining them as plant material. By taking up and holding nutrients during the summer, wetlands decrease the possibility of contamination downstream (Figure 1).

Water quality for agriculture

Leaching, on the other hand, is a basic step in production even for water of the best quality and must be practised when necessary to avoid salt accumulation that could ultimately affect production. Leaching can only be done, however, if the drainage below the crop root zone is sufficient to prevent a rise in the water table so that it is not a source of salt by itself.

Crop and Fertilizer Management Practices to Minimize

Nitrogen (N) is important for optimal crop production. Although most N fertilizers used in Montana do not contain nitrate, they quickly convert to nitrate in soil. Nitrate is a form of N that is available for plant uptake. It is highly soluble and easily lost to leaching as water moves through the soil profile.

In Example 1, the leaching fraction and water quality are used to predict drainage water quality. The plant, however, is only exposed to this drainage water salinity at the lowest part of the root zone. The salinity in this lower portion of the root zone tends to be higher than in the upper portion due to its much lower leaching fraction.

Nitrate leaching only occurs when water is passing through the soil, so the extent of nitrate leaching is related to the amount of water percolation.
