WebGoldSim itself cannot (under most circumstances) do this. But this is precisely what geochemical models (such as PHREEQC) do. Note: Geochemical models such as PHREEQC can do more than just solve the chemical equilibria equations. WebJan 1, 2024 · Solution: Use DLL to link to PHREEQC. Steps for Setup Step 1: Define species and starting solutions (must be charge-balanced) Step 2: Build the GoldSim model with the DLL element Step 3: Define the DLL element properties Input to external DLL (PHREEQC): Species vector (inarg []) Output from external DLL (PHREEQC): New …
WebGoldSim has been used extensively in the mining industry worldwide to address a broad range of issues, including: Mine water management; … WebAdvisian was retained to provide field sampling services, GoldSim model development and programming within C++ to dynamically link Phreeqc water chemistry modeling at each timestep. Over the course of the project, complete site walkdowns were held to identify and quantify wastewater streams leaving the plant and entering environmental discharges.
Linking of GoldSim to the geochemical software PHREEQC offers opportunities to account for the effects of complex aqueous chemical processes in water balance models. There are two approaches for making the linkage based on implementation of GoldSim’s External element that has an interface to Dynamic … See more A description and example of the C++ approach has been in the GoldSim model for a few years. That model has been slightly revised to use time-varying water chemistry and less erratic water flows. It has also been … See more In recent years, new releases of the PHREEQC software have included the object-oriented IPHREEQC modules that can be directly used by other software such as Python. This … See more To implement either of the approaches used in these models, the user should have a good working knowledge of PHREEQC and … See more The examples models simulate mixing of an acidic and an alkaline water flowing into a pond. Both the flow rates of the two streams and the water chemistries vary with time. Chemical equilibrium is assumed to be … See more WebMar 31, 2024 · Experience: Experience with water balance modeling (including volumes and chemistry), including creation, maintenance, and updates is viewed as a strong asset. Prior experience with GoldSim and PHREEQC is preferred. Operational, process development, or laboratory experience with validated water improvements implemented.
