Chapter One — The Engineering Case for FRP in Mining and Mineral Processing
Resilient Infrastructure for Iran's Mines; FRP and GRP Profiles in the Mining Industry
Iran's mining industry — from copper mines such as Sarcheshmeh and Miduk, to iron ore mines like Gol-e-Gohar
and Chadormalu, and the lead-zinc and coal mines of Alborz and Kerman — faces a combination of
severe abrasion from rock and ore particles, mining dust, moisture and acid mine drainage (AMD),
continuous vibration from crushers and conveyors, and remote locations with limited access to cranes and
heavy equipment. In this environment, metal structures quickly suffer abrasion, corrosion, and high
transport and repair costs at remote sites. Nabak Composite's FRP and GRP
profiles — with their abrasion resistance, chemical resistance, electrical insulation, and light weight —
offer an engineered solution for conveyor platforms, crusher grating flooring, handrails, and cable trays in
processing plants across Iran's mines.

1Why the Mining Environment Is Harsh on Metal
Metal Structures in Mines and Processing Plants
- Rapid surface abrasion from continuous contact with dust and rock particles
- Severe corrosion from acid mine drainage and processing plant moisture
- Electrical safety risk near live plant equipment
- Heavy weight; costly and difficult to transport to remote, mountainous mines
- High repair costs and production downtime for periodic maintenance at remote sites
Nabak Composite FRP / GRP Profiles
- High abrasion resistance from a surface veil layer against mining dust
- Chemical resistance of the resin to acid drainage and processing moisture
- Fully electrically insulating; safe for processing plants and mine electrical rooms
- Lightweight; transportable by light vehicles to remote mines without a crane
- Reduced repair cycles and production downtime at hard-to-reach sites

of a Conveyor Access Platform application where abrasion resistance, light weight for
transport to remote sites, and electrical safety all matter simultaneously.

2Five Key Engineering Properties for Mining
Selecting FRP for mining, unlike industries such as oil and gas, requires one additional property that stems
specifically from the nature of mining operations: abrasion resistance against continuous
contact with mining dust and rock particles, achieved by adding a wear-resistant surface veil layer and
selecting the appropriate resin. Alongside this, chemical resistance to acid mine drainage
(whose pH can be severely acidic and destroy steel within a few years), electrical insulation
for processing plant safety, light weight relative to strength for transport to Iran's
mountainous, remote mines without heavy cranes, and long-term durability under the
round-the-clock, continuous production cycles of mining operations, complete this engineered solution.

Resin selection (vinyl ester for direct exposure to acid drainage and mine tailings, or isophthalic
polyester for general platform and walkway applications) is recommended by Nabak Composite's technical
department based on the specific conditions of the mine and ore.

Why Conveyor Platforms and Processing Plants Are the Top Priority for FRP in Mining
Conveyors and processing plants are where three risks converge simultaneously: continuous abrasion from
ore dust, moisture and acidity from processing operations (particularly in copper leaching and flotation
units), and the need for electrical insulation near motor rooms and switchgear. FRP flooring, handrails,
and cable trays address all three risks at once; the light weight of the profiles also makes transport to
Iran's mountainous, remote mines possible without heavy cranes.

Industry PerspectiveMining Engineer
From a mining engineering perspective, FRP's abrasion resistance to continuous ore dust reduces the
need for periodic replacement of flooring and conveyor platforms in high-throughput mines. The resin's
chemical resistance to acid mine drainage (which, in copper leaching and flotation units with low pH,
can destroy steel within a short period) extends the service life of processing plant structures. More
importantly, the light weight of the profiles enables transport to Iran's mountainous, remote mines —
with limited access roads and no possibility of deploying heavy cranes — using light vehicles and a
limited workforce, an important factor in substantially reducing the logistics costs of mining
projects.
Fast installation with hand tools and lightweight components at remote sites; reduced reliance on cranes and heavy machinery for transport and installation.
A full range of standard sections (angle, channel, beam, grating) for the integrated design of conveyor platforms, handrails, and processing plants.
Mechanical and load-bearing specifications compliant with international standards, suitable for reference in load analysis of conveyor platforms and mine stairways.

Full electrical insulation and the anti-slip surface of the grating reduce the risk of falls and electric shock in the dusty, humid mining environment.
