Yes. And this is regarding the potash. Of course, we are -- now we have a very unique situation in the market where prices are going up very high. You can expect prices probably during second semester this year, especially fourth quarter, probably as an average close to double than the prices -- average prices of second half last year. It means it's a significant increase in pricing.
We don't know and we don't have enough information today, as we speak, to have long-term projections about what's going on with the potash prices. There's a lot of researchable potash, we can check it on it. And see -- I think there's a lot of these uncertainties regarding what's going on in the long term, but in the short term, prices are very, very good in the potash.
We are pushing our volume. As we put in our press release, we will try to increase our volumes in the second half and we will, and getting the benefit of the better price environment. It means that margins from potash second half will be significantly higher than first half and significantly higher of any half for the last 3 years maybe.
We are very positive about what's going on in the potash industry for second half this year. And for me, it's too early now to give you an outlook about the volume for next year. As you know, we have this mixed production of lithium and potash in the Salar de Atacama. We are now working on our business plan and operational planning in the Salar in order to know what is going to be the total volume of available potash for sale next year.
Keep in mind that the main use of our potash and the most important one is to be raw material of potassium nitrate, we're working in our business plan [indiscernible] next year. Both prices of potash are going in the right direction. Of course, potassium nitrate is going in the right direction, too. As we mentioned before many times, we're not as volatile as potash. It means when potash goes down, we don't go down in the same level, and we don't go up in the same level. But anyway, prices of potassium nitrate in the second half of this year is going to be significantly higher than first half, that's very good news. But I expect to have more information or more data regarding what we expect for next year in the next conference call after September.
Regarding your last question, that is not an easy question, the political situation. As you mentioned, we are in the middle of an electoral year in Chile. So it is reasonable to hear many statements on many different issues. In my opinion, it's not prudent for companies to get involved in political discussions, of course, not. However, I think it's important to remember some key facts, in my opinion, about SQM and the Salar de Atacama operation, very few.
The first one or the first point in our opinion regarding what we think is the Salar operation's, I mean, story is. As you may remember, it's an old story but Salar del Atacama project was better internationally by CORFO the mid-80s, if I'm not wrong, it was in 1986 or 1985, something like that. And was awarded by an American and Chilean company at that time. The American company, if you remember, was Amax. Amax was, I remember, one of the largest mining companies in the U.S. at that time, and the Chilean company, if I'm not wrong, was Molymet. The main conditions to operate Salar de Atacama were set in that process in 1986. SQM, of course, was not involved by role. But after 7 years, more or less 7 years, so this investment, research and development, whatever, in the project in 1983, I'm sure it was 1983. These companies decided to sell the participation in the project, which is when SQM bought the project. Of course, inheriting the same conditions agreed by these companies with CORFO 7 years ago.
Finally, as you may remember, in 2018, during the previous government, an amendment to the contract was signed between CORFO and SQM, mainly decreasing the lithium project that was the area we were looking for. But of course, in exchange of a healthier economic conditions in favor of CORFO.
Currently, as you know, the lithium industry in Chile and prices and delivering resources to the country according to the agreement with CORFO, which are close to 50% of the gross margin generated by this business. It means, to be clear, there are no other economic activity in Chile that pays more taxes and contributes with higher resources as a percentage of its margins. That's a real situation of the project today.
The second point I want to -- to be very clear is that we add a lot of value to the minerals in the Salar del Atacama on a sustainable way. As everyone knows, we are one of the few lithium producers in the world that is integrated in the mining instruction and subsequent refinement of the product into extremely high-quality lithium carbonate and lithium hydroxide. We add value in such a way that it can be used directly in high-tech industry, such as electric vehicles.
As we know, most Australian players extract the mineral and then sell the raw material to China, where the value-added process of producing refined lithium products is done. In less than 2 years, we have more than doubled our capacity and are already working to almost double in just a few years at the same time. But at the same time, we're reducing our brine structures, increasing yields in what is an unprecedented way. We are very, very proud about it.
Finally, let me tell, Cesar, that we will keep working on initiatives like this. We're committed to producing lithium and all our products -- and all of our products in a sustainable way, adding value to all our stakeholders.
