Copper smelters are relying on by-product sulfuric acid revenues to offset losses from negative concentrate treatment charges. Strong acid prices are supporting smelter profitability, with prices remaining elevated. The trend underscores the key role of sulfuric acid in smelter economics and suggests continued price strength.
A Strait of Hormuz blockade and export bans from Russia and Kazakhstan severely curtailed sulfur supply, pushing global sulfuric acid prices to multi-year highs. The Chinese smelter acid index gained 94% and CFR Indonesia sulfuric acid rose 185% in H1. Despite a post-ceasefire retreat, inventories remain low and supply recovery is slow, keeping prices elevated.
Aluminium sulfate prices followed a firm trend in Q1 2026 as feedstock and logistics pressure outweighed moderate downstream demand. In Asia, India recorded a 5.24% increase from Q4 2025 to Q1 2026, while prices rose 6.99% from January to March 2026. The increase was supported by higher sulfuric acid-related cost pressure, steady demand from water treatment and paper applications, and freight uncertainty linked to the Iran war. In Europe, the United Kingdom showed a more moderate rise, with aluminium sulfate prices increasing 4.02% from Q4 2025 to Q1 2026 and 5.33% from January to March 2026. Demand from municipal water treatment and industrial effluent treatment stayed stable, while energy and logistics costs kept producers cautious. In North America, the USA posted the strongest increase, with prices rising 15.53% from Q4 2025 to Q1 2026 and 12.60% from January to March 2026. The sharper movement reflected stronger cost pass-through, steady water-treatment demand, and broader chemical logistics pressure.
Analyst Insight
According to Procurement Resource, near-term aluminium sulfate prices may remain firm if sulfuric acid, energy, and freight costs stay elevated, while demand is expected to remain steady across water treatment and industrial applications.

During the second half of 2025, the aluminium sulfate market in India followed a mixed but overall firm trajectory, with prices moving from approximately 285 USD/MT (FOB) in July to around 283 USD/MT in December. The market initially witnessed a slight decline in Q3 due to adequate supply and moderate demand from the water treatment, paper, and textile sectors. However, prices recovered toward the latter part of the quarter as demand from municipal water treatment and industrial applications improved. In Q4, the market maintained a steady upward trend, supported by consistent downstream consumption and firm input costs, which helped sustain pricing levels.
In the United Kingdom, the aluminium sulfate prices displayed a stable to slightly upward trend during H2 2025, increasing from around 332 USD/MT (CFR) in July to approximately 335 USD/MT in December. The market experienced early softness in Q3 due to comfortable supply conditions, followed by stabilization and gradual recovery as demand from water utilities and industrial sectors improved. During Q4, prices continued to rise modestly, reflecting balanced supply-demand fundamentals and steady consumption patterns.
In the United States, aluminium sulfate prices followed a clear upward trajectory, rising from about 395 USD/MT (CIF) in July to around 421 USD/MT in December. The market remained supported by strong demand from municipal water treatment, pulp and paper, and food processing industries. While Q3 saw steady price increases driven by active procurement, Q4 witnessed further gains as supply tightened slightly, and production costs remained firm.
Aluminium Sulfate is a water-soluble white crystalline solid, and it is primarily used as a coagulating agent in the purification of drinking water and sewage treatment plants. Its anhydrous form occurs naturally as a millosevichite mineral found near volcanic sites. Aluminium Sulfate usually occurs in its hydrate form, mainly as hexadecahydrates or octadecahydrates. Aluminium Sulfate is often referred to as alum which has been used as a flocculating agent since immemorial. The alum is a hydrated aluminium sulfate salt with a monovalent cation often substituted by potassium or ammonium.

Alum schists (a type of metamorphic rock) are a mixture of iron pyrite, aluminium silicate, and various bituminous substances. These are roasted, and during the process, the sulfuric acid obtained reacts with clay to form a product mixture containing aluminium sulfate. The mixture is subjected to further treatment to remove the impurities. The mixture is mixed with water and allowed to stand for water-soluble impurities to separate. Additionally, it is subjected to evaporation so that iron sulfate crystals separate, leaving the desired aluminium sulfate.
