Abstract. The objective of process control in the mineral industry is to optimise the recovery of the valuable minerals, while maintaining the quality of the concentrates delivered to the metal extraction plants. The paper presents a survey of the control approaches for ore size reduction and mineral separation processes.

This paper briefly evaluates the advantages and disadvantages of basic dust control techniques presently used by the U.S. coal preparation and mineral processing plants. These include ventilation, baghouse-type collectors, wet scrubbers, elastrostatic precipitators, source control, sprays, good housekeeping, and personal protection devices.

Most parts of mineral processing and metallurgical plants exhibit a certain level of control system (Process Intelligence-PI) that stores the operational information and assists in automating such ...

Measurement and intelligent control in mineral processing plant is the technology that is used to automatically measure, analyze, and control the key process …

These specific publications were selected based on their subject-area focus (i.e. mineral processing and associated chemical, control and process engineering principles) rather than their technique focus (e.g. publications focused on the development of new machine learning techniques independent of intended use in minerals engineering).

Model Predictive Control (MPC) is an advanced technique for process control that has seen a significant and widespread increase in its use in the process industry since its introduction. In mineral processing, in particular, several applications of conventional MPC can be found for the individual processes of crushing, grinding, …

The efficient and effective operation of mineral and mining processing plants is crucial. Instrumentation & control systems are vital in optimising these operations, ensuring safety, accuracy, and increased productivity. This blog explores the significance of these systems in the mining and mineral processing industries.

This enables construction of a flotation process control system in the mineral processing plant, which is based on the recognition of images of the flotation froth. The IR algorithms do not provide stable image recognition results and are not efficient in the situation where the parameters of the flotation process are highly unstable.

Operations of an aggregates processing plant are mainly controlled by operators in control rooms which usually aim to keep the process operations up and running effectively for as long as possible ...

Abstract. This chapter begins with some general observations on the strategic importance automation technologies have acquired in the mining business, and then reviews a series of recently available commercial advanced sensors for grinding and flotation plants. This is followed by a brief look at developments in advanced control and the main ...

According to research from the University of Pretoria, more than 75% of Minerals Processing Plants are still using basic control strategies. Advanced process control is a software tool that collects information from the process / field (supervision, historians, and control systems) applies the right control strategy (according to the …

The value of process control has become widely recognized in the mineral processing industry. In the last 40 years, the industry has strived to maximize the capacities of such process control systems. Despite this sustained effort, advancement has not always resulted in the plant performance expected.

It is based on population balance modeling and is an extension of previous works. The basic regulatory control (BRC) system comprises only single-input–single-output control loops with proportional–integral (PI) controllers and operates at a fixed feed rate. ... Mineral processing plants remain nowadays infamous for their low energy ...
