Mining production and solid waste disposal LCIA model

The LICYMIN model is a tool designed to build a detailed and change-oriented Life Cycle Assessment System for mining. Three are three subsystems into which the mining system is broken down, and are covered by this model, namely Extraction (Production), Mineral Processing and Waste Remediation. The present model offers the means to the LCA practitioner to handle, manipulate, organise and analyse large amount of mining data; as well as present the results in a coherent manner. However, the conceptualisation of the LCA study and quality of the data used rest entirely on the LCA practitioner.

The LCIA model interacts closely with the LCA database, which is the one responsible to store the data on the system under study; provide information for the LCA study itself, such as category indicators and factors; to provide subprograms and factors to estimate missing or poorly recorded environmental emissions during production phase, such as blasting fumes. This database was developed within the object-relational database concept model, using the software Oracle 9i Enterprise Edition. The LCA database consists of forty-four object types, forming twenty seven object tables.

The display of results and/or information stored in the LCA database is carried out using the Oracle 9i Report Builder Developer tool.
