14.1 Introduction. Potassium (K) was first isolated in 1807 by Sir Humphrey Davy. The word "potash" is often used to refer to potassium chloride (KCl), a common K fertilizer and derivative from "pot ashes" which refers to the earliest practice of applying the leachate of wood ashes as a source of K.

This paper presents a dynamic model that describes, with minor changes, the carbon-in-leach, the carbon-in-pulp, and the gold leaching processes.

The dynamic change of P concentration in leaching water was different. Wang [ 24 ] believed that TP concentration reached its maximum after 1–2 weeks of P application.

Nutrient dynamics in soil (biogeochemistry) are critical to determining soil and plant function (health) both in terms of nutrients (e.g. nutrient addition from litter and loss via leaching) and physical structure (e.g. compacting or cracking). Nutrients enter the soil via rainfall, leaf litter and debris inputs from surface vegetation, and the erosion of minerals …

Stanford himself acknowledged that this approach "… largely ignores the dynamic nature of the water-soil-plant-nitrogen system". Dynamic simulation models of soil and crop processes have the potential for estimating N dynamics and crop fertilizer needs (Melkonian, van Es, DeGaetano, Sogbedji, & Joseph, 2007; Puntel et al., 2016; …

ABSTRACT. A project-level dynamic model has been developed to simulate heap leach operations from ore handling through to final product. The model deals with the long-term effects of leach recovery rates, solution management, inventory build-up, complex reaction chemistry, and the limitations of the downstream process plant.

effects of inhibitors and biochar on the major N dynamics in excreta patches. Thus, we analyzed the results of 44 studies (156, 65, 67, and 97 comparisons of N 2O emissions, NO 3 − leaching, plant N uptake, and plant yields, respectively) to evaluate the effects of additives on N losses and uptake from excreta patches.

Increasing DCD rate coincided with increased effectiveness in NH 4 +-N retention (Fig. 3 a) and plant N uptake, which led to a decrease in leaching of NH 4 +-N, NO 3 −-N and total N (Table 4). Application of DCD to urine-affected pasture in late-autumn was effective in reducing peak NO 3 − -N concentration in leachate, as reported by …

The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of annual copper production over the past 10 years. This level of production has been achieved through and supported by the use …
