Who do you trust?
An independent, technology service to verify and benchmark mining process chemistry. For Chemical Suppliers and Minerals & Mining industry.
Process variance is a result of the interaction of multiple factors or variables. If allowed to drift over time or, suddenly change adversely, it can result in significant losses to the mine site. Process Chemistry Analytics (PCA) focuses on the mining process chemistry, whilst also considering the effect of other production factors. Some important factors are changes in chemical treatment, personnel or supplier. Changes in plant, raw materials, water quality, equipment, control strategies, chemical addition points, dilution, hydrodynamics and other operational factors.
For mine sites that need to optimise thickener throughput, underflow density, leaching performance, recovery, profitability and environmental compliance, this mining chemistry analytics service assists in separating out the effects of your process chemistry from the many other production and mechanical factors.
In order to make decisions with confidence, management of mine sites need reliable data with actionable conclusions that can be trusted. PCA is independent of any chemical supplier and provides an impartial assessment. PCA applies industry process chemistry knowledge, advanced data management, statistical and graphical techniques to verify and benchmark your process chemistry and summarise results in a PCA report.
All PCA reports are based on the site’s own production data, where permission has been given to use such data, whether from online process control sensors or manually collected data sets. High security cryptography is used to prove a PCA report originated from PCA and has not been altered by a third party (digitally signed SHA-256 checksum, as designed by the United States National Security Agency – the same technique that software distributors use to verify the integrity of file downloads).
Therefore, the client can have confidence it is the original report from PCA, based on the mine site’s own data.
Service Reports for Chemical Suppliers
Enhanced service reports on your chemical treatment. These can be on a monthly, bimonthly or less frequent basis. For example, for review meetings with your customer. Benefit from this independent service from PCA to demonstrate to your customer that you have confidence in your chemical treatment.
Reports on Plant Trials of New Chemical Treatments
These can be prepared for the chemical supplier or the mine site or both. Typically they involve comparing production performance before, during and after the trial. They enable you to reliably quantify the effects of a new chemical treatment.
These can be prepared for the chemical supplier or the mine site or both. For example, to compare performance of one mine process at different times. Or, with permission, to compare performance of a specific chemical treatment at two or more similar mine sites. What is the industry average performance for a specific chemical treatment? What is the variance in performance?
Trouble Shooting Reports
For those times when the site is unhappy with current performance and needs to diagnose mine chemistry issues.
In most cases, the aim is to compare different periods of production. These periods need to be defined for some specific mine chemistry to be investigated. For example, questions about the effects of a change in mine chemistry or control strategy. Based on years of process chemistry consulting experience in industry, the founder of PCA holds discussions with the client to define the objectives and scope of work. Any mine process chemistry issues that need investigating and the types of process data available at the site are discussed. The specific unit processes to focus on are defined. If the client is concerned about data security, PCA can sign a Non-Disclosure Agreement.
When PCA has an ongoing contract with the client, PCA is able to review and compare fresh production data with historical periods. This enables issues to be identified earlier and is therefore recommended. The founder of PCA is available to discuss each report and the implications for the mine chemistry. A database is accumulated over time that can be used to benchmark your mine process and identify optimum mining chemistry parameters. In most cases, we are looking to identify conditions with the best average performance, whilst minimising the process variance. Management can then decide what actions to take to improve mine chemistry performance.
The previously defined, relevant mine chemistry data is uploaded by the client to PCA’s cloud storage using a customised form in their web browser (if you have slow, unreliable Internet, other methods can be used for sending large data sets). PCA is using the latest, high security Google infrastructure, where data is end-to-end and endpoint encrypted. Only PCA can access the data. Data sharing is controlled by PCA using administrator privileges. Customised data collection forms are available to the client for logging key changes in mine chemistry and, the data stored in the PCA cloud ready for analytics reporting.
Based on the previously defined mine chemistry objectives, the data is processed through data management and statistical algorithms to produce a PCA report. This report summarises the mine process data to highlight statistically significant differences between production periods and mine chemistry. The aim is to answer questions by interpreting the data at a deeper level and provide recommendations that management can action. Sometimes, the analytics raises more questions, but the aim is to identify answers, or at least potential answers that can be tested. PCA uses the leading, trusted advanced analytics tools, for example R, Python, Bash, SAS and others. PCA reports are digitally signed to prove they originate from PCA and have not been altered by a third party. The signature can be verified by the client or PCA.
Trust Independent PCA
Get started today by sending your business enquiry. PCA is independent of any chemical supplier and bases its analytics on mine process chemistry knowledge and the mine site’s own data. Each chemical treatment is assessed in an impartial, objective manner. The founder of PCA has decades of experience in process chemistry technical consulting for multinationals in the Chemical and other industries, such as Minerals & Mining, Pulp & Paper, Metals, Alumina, Food & Beverage. Work directly with the founder of PCA, not an intermediary. Trust in a positive outcome.
Why Choose PCA?
PCA is independent of any chemical supplier and has no interest in selling a particular chemical treatment. That is for the chemical supplier! PCA provides objective assessments of mine process chemistry performance using mine process chemistry knowledge and the mine site’s own data, rather than data generated by the chemical supplier. Data you are more likely to trust.
If you are a chemical supplier, utilise this independent service from PCA to demonstrate to your customer that you have confidence in your chemical treatment. If you are a mine site, utilise this service to verify, benchmark and improve your mine process chemistry performance.
You work directly with the founder of PCA, not an intermediary. Therefore, you can be assured of getting the best from PCA to ensure the ongoing success of your business. For PCA, that means providing your business with an excellent mining chemistry analytics service.

VisIt's Scatter plot allows for the visualisation of multivariate data of up to four dimensions
The Scatter plot takes multiple scalar variables and uses them for different axes in phase space. The different variables are combined to form coordinates in the phase space and they are displayed using glyphs and coloured using another scalar variable.

Data fusion involves techniques that combine data from multiple sources (dimension #1 & #2) and gather that information in order to achieve inferences (see scatter plot)
Image of random data plus trend, with best-fit line and smoothing curves
The data is 1000 points, with a trend of 1-in-100, with random normal noise of SD 10 superimposed. The r2 fit of the raw data is 0.08; of the 10-pt-smoothed, 0.57; of 100-pt-smoothed, 0.97. For the raw data, the simple trend line explains almost none of the variance of the time series (only 8%). For the 100-pt filtering, the trend line explains almost all of the data (97%). The trend lines are almost identical as are the confidence levels. It shows that a low r2 value should not be interpreted as evidence of lack of trend.
