Scoping Study

·          JKTech engineers (one mining, one processing) visit site to assess sampling needs and develop site specific procedures

·          Select the primary ore types and domains to be surveyed.  Review the blast design and plant performance of each domain

·          Collect geotechnical data on chosen domains

·          Discuss detail of the blast monitoring and plant audit and plan the logistics for the blasting and grinding surveys

·          Prepare report which details the objectives and scopes of work for the Mine-to-Mill Project

 

Analysis

Blasting Survey

·          Collect representative samples and conduct structural mapping in the proposed domain

·          Review blast design and take high speed video of the blast

·          Measure explosive properties

·          Estimate ROM size distribution from digital photographs of muckpiles and back of trucks

Grinding Survey

·          Conduct surveys around the grinding circuit for each ore domain

·          Collect data on the operating conditions of the grinding circuit

·          Collect feed samples for JKBreakage tests

·          Determine full size analysis and percent solids on all slurry samples

JKSimBlast Modelling

·          Conduct rock mechanics laboratory tests

·          Estimate the rock mass blastability of the proposed domain

·          Using blast audit, blast monitoring data, blastability and ROM fragmentation, develop a blasting model using JKSimBlast for calibrating and refining blasts

JKSimMet Modelling

·          Conduct JKBreakage tests

·          Using grinding survey data, testwork results and Split-OnlineTM data, develop a JKSimMet simulation model of the grinding circuit to predict circuit performance

Optimisation

·         Using the JKSimBlast and JKSimMet models in collaboration with the client, investigate blasting and milling scenarios to predict the operating conditions that provide maximum efficiency and minimum costs

·          Recommend a course of action to the client to achieve optimum operating conditions
